Toward a positive vision of the future

Jun 22 JDN 2460849

Things look pretty bleak right now. Wildfires rage across Canada, polluting the air across North America. Russia is still at war with Ukraine, and Israel seems to be trying to start a war with Iran. ICE continues sending agents without badges to kidnap people in unmarked vehicles and sending them to undisclosed locations. Climate change is getting worse, and US policy is pivoting from subsidizing renewables back to subsidizing fossil fuels. And Trump, now revealed to be a literal fascist, is still President.

But things can get better.

I can’t guarantee that they will, nor can I say when; but there is still hope that a better future is possible.

It has been very difficult to assemble a strong coalition against the increasingly extreme far-right in this country (epitomized by Trump). This seems odd, when most Americans hold relatively centrist views. Yes, more Americans identify as conservative than as liberal, but Trump isn’t a conservative; he’s a radical far-right fascist. Trump recently gave a speech endorsing ethnic cleansing, for goodness’ sake! I’m liberal, but I’d definitely vote for a conservative like Mitt Romney rather than a Stalinist! So why are “conservatives” voting for a fascist?

But setting aside the question of why people voted for Trump, we still have the question of why the left has not been able to assemble a strong coalition against him.

I think part of the problem is that the left really has two coalitions within it: The center left, who were relatively happy with the status quo before Trump and want to go back to that; and the far left, who were utterly unhappy with that status quo and want radical change. So while we all agree that Trump is awful, we don’t really agree on what he’s supposed to be replaced with.

It’s of course possible to be in between, and indeed I would say that I am. While clearly things were better under Obama and Biden than they have been under Trump, there were still a lot of major problems in this country that should have been priorities for national policy but weren’t:

  1. Above all, climate change—the Democrats at least try to do something against it, but not nearly enough. Our carbon emissions are declining, but it’s very unclear if we’ll actually hit our targets. The way we have been going, we’re in for a lot more hurricanes and wildfires and droughts.
  2. Housing affordability is still an absolute crisis; half of renters spend more than the targeted 30% of their income on housing, and a fourth spend more than 50%.Homelessness is now at a record high.
  3. Healthcare is still far too expensive in this country; we continue to spend far more than other First World countries without getting meaningfully better care.
  4. While rights and protections for LGB people have substantially improved in the last 30 years, rights and protections for trans people continue to lag behind.
  5. Racial segregation in housing remains the de facto norm, even though it is de jure illegal.
  6. Livestock remain exempted from the Animal Welfare Act and in 2002 laboratory rats and mice were excluded as well, meaning that cruel or negligent treatment which would be illegal for cats and dogs is still allowed on livestock and lab rats.
  7. Income and wealth inequality in this country remains staggeringly high, and the super-rich continue to gain wealth at a terrifying rate.
  8. Our voting system is terrible—literally the worst possible system that can technically still be considered democracy.

This list is by no means exhaustive, but these are the issues that seem most salient to me.

2 and 3 both clearly showed up in my Index of Necessary Expenditure; these costs were the primary reason why raising a family of 4 was unaffordable on a median household income.

So it isn’t right to say that I was completely happy with how things were going before. But I still think of myself as center left, because I don’t believe we need to tear everything down and start over.

I have relatively simple recommendations that would go a long way toward solving all 8 of these problems:

Climate change could be greatly mitigated if we’d just tax carbon already, or implement a cap-and-trade system like California’s nationwide. If that’s too politically unpalatable, subsidize nuclear power, fusion research, and renewables instead. That’s way worse from a budget perspective, but for some reason Americans are just fanatically opposed to higher gas prices.

Housing affordability is politically thorny, but economically quite simple: Build more housing. Whatever we have to do to make that happen, we should do it. Maybe this involves changes to zoning or other regulations. Maybe it involves subsidies to developers. Maybe it involves deploying eminent domain to build public housing. Maybe it involves using government funds to build housing and then offering it for sale on the market. But whatever we do, we need more housing.

Healthcare costs are a trickier one; Obamacare helped, but wasn’t enough. I think what I would like to see next is an option to buy into Medicare; before you are old enough to get it for free, you can pay a premium to be covered by it. Because Medicare is much more efficient than private insurance, you could pay a lower premium and get better coverage, so a lot of people would likely switch (which is of course exactly why insurance companies would fight the policy at every turn). Even putting everyone on Medicare might not be enough; to really bring costs down, we may need to seriously address the fact that US doctors, particularly specialists, are just radically higher-paid than any other doctors in the world. Is an American doctor who gets $269,000 per year really 88% better than a French doctor who gets $143,000?

The policies we need for LGBT rights are mostly no-brainers.

Okay, I can admit to some reasonable nuance when it comes to trans women in pro sports (the statistical advantages they have over cis women are not as clear-cut as many people think, but they do seem to exist; average athletic performance for trans women seems to be somewhere in between the average for cis men and the average for cis women), but that’s really not a very important issue. Like, seriously, why do we care so much about pro sports? Either let people play sports according to their self-identified gender, or make the two options “cis women” and “other” and let trans people play the latter. And you can do the same thing with school sports, or you can eliminate them entirely because they are a stupid waste of academic resources; but either way this should not be considered a top priority policy question. (If parents want their kids to play sports, they can form their own leagues; the school shouldn’t be paying for it. Winning games is not one of the goals of an academic institution. If you want kids to get more exercise, give them more recess and reform the physical education system so it isn’t so miserable for the kids who need it most.)

But there is absolutely no reason not to let people use whatever pronouns and bathrooms they want; indeed, there doesn’t really seem to be a compelling reason to gender-segregate bathrooms in the first place, and removing that segregation would most benefit women, who often have to wait much longer in line for the bathroom. (The argument that this somehow protects women never made sense to me; if a man wants to assault women in the bathroom, what’s to stop him from just going into the women’s bathroom? It’s not like there’s a magic field that prevents men from entering. He’s already planning on committing a crime, so it doesn’t seem like he’s very liable to held back by social norms. It’s worthwhile to try to find ways to prevent sexual assault, but segregating bathrooms does little or nothing toward that goal—and indeed, trans-inclusive bathrooms do not statistically correlate with higher rates of sexual assault.) But okay, fine, if you insist on having the segregation, at least require gender-neutral bathrooms as well. This is really not that difficult; it’s pretty clearly bigotry driving this, not serious policy concerns.

Not exempting any vertebrate animals from anti-cruelty legislation is an incredibly simple thing to do, obviously morally better, and the only reason we’re not doing it is that it would hurt agribusinesses and make meat more expensive. There is literally zero question what the morally right thing to do here is; the question is only how to get people to actually do that morally right thing.

Finally, how do we fix income inequality? Some people—including some economists—treat this as a very complicated, difficult question, but I don’t think it is. I think the really simple, obvious answer is actually the correct one: Tax rich people more, and use the proceeds to help poor people. We should be taxing the rich a lot more; I want something like the revenue-maximizing rate, estimated at about 70%. (And an even higher rate like the 90% we had in the 1950s is not out of the question.) These funds could either provide services like education and healthcare, or they could simply be direct cash transfers. But one way or another, the simplest, most effective way to reduce inequality is to tax the rich and help the poor. A lot of economists fear that this would hurt the overall economy, but particularly if these rates are really targeted at the super-rich (the top 0.01%), I don’t see how they could, because all those billions of dollars are very clearly monopoly rents rather than genuine productivity. If anything, making it harder to amass monopoly rents should make the economy more efficient. And taking say 90% of the roughly 10% return just the top 400 billionaires make on their staggering wealth would give us an additional $480 billion per year.

Fixing our voting system is also quite straightforward. Ranked-choice voting would be a huge improvement, and has already been implemented successfully in several states. Even better would be range voting, but so far very few places have been bold enough to actually try it. But even ranked-choice voting would remove most of the terrible incentives that plurality voting creates, and likely allow us to move beyond the two-party system into a much more representative multiparty system.

None of this requires overthrowing the entire system or dismantling capitalism.

That is, we can have a positive vision of the future that doesn’t require revolution or radical change.

Unfortunately, there’s still a very good chance we’ll do none of it.

Why is America so bad at public transit?

Sep 8 JDN 2460562

In most of Europe, 20-30% of the population commutes daily by public transit. In the US, only 13% do.

Even countries much poorer than the US have more widespread use of public transit; Kenya, Russia, and Venezuela all have very high rates of public transit use.

Cities around the world are rapidly expanding and improving their subway systems; but we are not here in the US.

Germany, France, Spain, Italy, and Japan are all building huge high-speed rail networks. We have essentially none.

Even Canada has better public transit than we do, and their population is just as spread out as ours.

Why are we so bad at this?

Surprisingly, it isn’t really that we are lacking in rail network. We actually have more kilometers of rail than China or the EU—though shockingly little of it is electrified, and we had nearly twice as many kilometers of rail a century ago. But we use this rail network almost entirely for freight, not passengers.

Is it that we aren’t spending enough government funds? Sort of. But it’s worth noting that we cover a higher proportion of public transit costs with government funds than most other countries. How can this be? It’s because transit systems get more efficient as they get larger, and attract more passengers as they provide better service. So when you provide really bad service, you end up spending more per passenger, and you need more government subsidies to stay afloat.

Cost is definitely part of it: It costs between two and seven times as much to build the same amount of light rail network in the US as it does in most EU countries. But that just raises another question: Why is it so much more expensive here?

This isn’t comparing with China—of course China is cheaper; they have a dictatorship, they abuse their workers, they pay peanuts. None of that is true of France or Germany, democracies where wages are just as high and worker protections are actually a good deal stronger than here. Yet it still costs two to seven times as much to build the same amount of rail in the US as it does in France or Germany.

Another part of the problem seems to be that public transit in the US is viewed as a social welfare program, rather than an infrastructure program: Rather than seeing it as a vital function of government that supports a strong economy, we see it as a last resort for people too poor to buy cars. And then it becomes politicized, because the right wing in the US hates social welfare programs and will do anything to make sure that they are cut down as much as possible.

It wasn’t always this way.

As recently as 1970, most US major cities had strong public transit systems. But now it’s really only the coastal cities that have them; cities throughout the South and Midwest have massively divested from their public transit. This goes along with a pattern of deindustrialization and suburbanization: These cities are stagnating economically and their citizens are moving out to the suburbs, so there’s no money for public transit and there’s more need for roads.

But the decline of US public transit goes back even further than that. Average transit trips per person in the US fell from 115 per year in 1950 to 36 per year in 1970.

This long, slow decline has only gotten worse as a result of the COVID pandemic; with more and more people working remotely, there’s just less need for commuting in general. (Then again, that also means fewer car miles, so it’s probably a good thing from an environmental perspective.)

Once public transit starts failing, it becomes a vicious cycle: They lose revenue, so they cut back on service, so they become more inconvenient, so they lose more revenue. Really successful public transit systems require very heavy investment in order to maintain fast, convenient service across an entire city. Any less than that, and people will just turn to cars instead.

Currently, the public transit systems in most US cities are suffering severe financial problems, largely as a result of the pandemic; they are facing massive shortfalls in their budgets. The federal government often helps with the capital costs of buying vehicles and laying down new lines, but not with the operating costs of actually running the system.

There seems to be some kind of systemic failure in the US in particular; something about our politics, or our economy, or our culture just makes us uniquely bad at building and maintaining public transit.

What should we do about this?

One option would be to do nothing—laissez faire. Maybe cars are just a more efficient mode of transportation, or better for what Americans want, and we should accept that.

But when you look at the externalities involved, it becomes clear that this is not the right approach. While cars produce enormous amounts of pollution and carbon emissions, public transit is much, much cleaner. (Electric cars are better than diesel buses, but still worse than trams and light rail—and besides, the vast majority of cars use gasoline.) Just for clean air and climate change alone, we have strong reasons to want fewer cars and more public transit.

And there are positive externalities of public transit too; it’s been estimated that for every $1 spent on public transit, a city gains $5 in economic activity. We’re leaving a lot of money on the table by failing to invest in something so productive.

We need a fundamental shift in how Americans think about public transit. Not as a last resort for the poor, but as a default option for everyone. Not as a left-wing social welfare program, but as a vital component of our nation’s infrastructure.

Whenever people get stuck in traffic, instead of resenting other drivers (who are in exactly the same boat!), they should resent that the government hasn’t supported more robust public transit systems—and then they should go out and vote for candidates and policies that will change that.

Of course, with everything else that’s wrong with our economy and our political system, I can understand why this might not be a priority right now. But sooner or later we are going to need to fix this, or it’s just going to keep getting worse and worse.

Israel, Palestine, and the World Bank’s disappointing priorities

Nov 12 JDN 2460261

Israel and Palestine are once again at war. (There are a disturbing number of different years in which one could have written that sentence.) The BBC has a really nice section of their website dedicated to reporting on various facets of the war. The New York Times also has a section on it, but it seems a little tilted in favor of Israel.

This time, it started with a brutal attack by Hamas, and now Israel has—as usual—overreacted and retaliated with a level of force that is sure to feed the ongoing cycle of extremism. All across social media I see people wanting me to take one side or the other, often even making good points: “Hamas slaughters innocents” and “Israel is a de facto apartheid state” are indeed both important points I agree with. But if you really want to know my ultimate opinion, it’s that this whole thing is fundamentally evil and stupid because human beings are suffering and dying over nothing but lies. All religions are false, most of them are evil, and we need to stop killing each other over them.

Anti-Semitism and Islamophobia are both morally wrong insofar as they involve harming, abusing or discriminating against actual human beings. Let people dress however they want, celebrate whatever holidays they want, read whatever books they want. Even if their beliefs are obviously wrong, don’t hurt them if they aren’t hurting anyone else. But both Judaism and Islam—and Christianity, and more besides—are fundamentally false, wrong, evil, stupid, and detrimental to the advancement of humanity.

That’s the thing that so much of the public conversation is too embarrassed to say; we’re supposed to pretend that they aren’t fighting over beliefs that obviously false. We’re supposed to respect each particular flavor of murderous nonsense, and always find some other cause to explain the conflict. It’s over culture (what culture?); it’s over territory (whose territory?); it’s a retaliation for past conflict (over what?). We’re not supposed to say out loud that all of this violence ultimately hinges upon people believing in nonsense. Even if the conflict wouldn’t disappear overnight if everyone suddenly stopped believing in God—and are we sure it wouldn’t? Let’s try it—it clearly could never have begun, if everyone had started with rational beliefs in the first place.

But I don’t really want to talk about that right now. I’ve said enough. Instead I want to talk about something a little more specific, something less ideological and more symptomatic of systemic structural failures. Something you might have missed amidst the chaos.

The World Bank recently released a report on the situation focused heavily on the looming threat of… higher oil prices. (And of course there has been breathless reporting from various outlets regarding a headline figure of $150 per barrel which is explicitly stated in the report as an unlikely “worst-case scenario”.)

There are two very big reasons why I found this dismaying.


The first, of course, is that there are obviously far more important concerns here than commodity prices. Yes, I know that this report is part of an ongoing series of Commodity Markets Outlook reports, but the fact that this is the sort of thing that the World Bank has ongoing reports about is also saying something important about the World Bank’s priorities. They release monthly commodity forecasts and full Commodity Markets Outlook reports that come out twice a year, unlike the World Development Reports that only come out once a year. The World Bank doesn’t release a twice-annual Conflict Report or a twice-annual Food Security Report. (Even the FAO, which publishes an annual State of Food Security and Nutrition in the World report, also publishes a State of Agricultural Marketsreport just as often.)

The second is that, when reading the report, one can clearly tell that whoever wrote it thinks that rising oil and gas prices are inherently bad. They keep talking about all of these negative consequences that higher oil prices could have, and seem utterly unaware of the really enormous upside here: We may finally get a chance to do something about climate change.

You see, one of the most basic reasons why we haven’t been able to fix climate change is that oil is too damn cheap. Its market price has consistently failed to reflect its actual costs. Part of that is due to oil subsidies around the world, which have held the price lower than it would be even in a free market; but most of it is due to the simple fact that pollution and carbon emissions don’t cost money for the people who produce them, even though they do cost the world.

Fortunately, wind and solar power are also getting very cheap, and are now at the point where they can outcompete oil and gas for electrical power generation. But that’s not enough. We need to remove oil and gas from everything: heating, manufacturing, agriculture, transportation. And that is far easier to do if oil and gas suddenly become more expensive and so people are forced to stop using them.

Now, granted, many of the downsides in that report are genuine: Because oil and gas are such vital inputs to so many economic processes, it really is true that making them more expensive will make lots of other things more expensive, and in particular could increase food insecurity by making farming more expensive. But if that’s what we’re concerned about, we should be focusing on that: What policies can we use to make sure that food remains available to all? And one of the best things we could be doing toward that goal is finding ways to make agriculture less dependent on oil.

By focusing on oil prices instead, the World Bank is encouraging the world to double down on the very oil subsidies that are holding climate policy back. Even food subsides—which certainly have their own problems—would be an obviously better solution, and yet they are barely mentioned.

In fact, if you actually read the report, it shows that fears of food insecurity seem unfounded: Food prices are actually declining right now. Grain prices in particular seem to be falling back down remarkably quickly after their initial surge when Russia invaded Ukraine. Of course that could change, but it’s a really weird attitude toward the world to see something good and respond with, “Yes, but it might change!” This is how people with anxiety disorders (and I would know) think—which makes it seem as though much of the economic policy community suffers from some kind of collective equivalent of an anxiety disorder.

There also seems to be a collective sense that higher prices are always bad. This is hardly just a World Bank phenomenon; on the contrary, it seems to pervade all of economic thought, including the most esteemed economists, the most powerful policymakers, and even most of the general population of citizens. (The one major exception seems to be housing, where the sense is that higher prices are always good—even when the world is in a chronic global housing shortage that leaves millions homeless.) But prices can be too low or too high. And oil prices are clearly, definitely too low. Prices should reflect the real cost of production—all the real costs of production. It should cost money to pollute other people’s air.

In fact I think the whole report is largely a nothingburger: Oil prices haven’t even risen all that much so far—we’re still at $80 per barrel last I checked—and the one thing that is true about the so-called Efficient Market Hypothesis is that forecasting future prices is a fool’s errand. But it’s still deeply unsettling to see such intelligent, learned experts so clearly panicking over the mere possibility that there could be a price change which would so obviously be good for the long-term future of humanity.

There is plenty more worth saying about the Israel-Palestine conflict, and in particular what sort of constructive policy solutions we might be able to find that would actually result in any kind of long-term peace. I’m no expert on peace negotiations, and frankly I admit it would probably be a liability that if I were ever personally involved in such a negotiation, I’d be tempted to tell both sides that they are idiots and fanatics. (The headline the next morning: “Israeli and Palestinian Delegates Agree on One Thing: They Hate the US Ambassador”.)

The World Bank could have plenty to offer here, yet so far they’ve been too focused on commodity prices. Their thinking is a little too much ‘bank’ and not enough ‘world’.

It is a bit ironic, though also vaguely encouraging, that there are those within the World Bank itself who recognize this problem: Just a few weeks ago Ajay Banga gave a speech to the World Bank about “a world free of poverty on a livable planet”.

Yes. Those sound like the right priorities. Now maybe you could figure out how to turn that lip service into actual policy.

Now is the time for CTCR

Nov 6 JDN 2459890

We live in a terrifying time. As Ukraine gains ground in its war with Russia, thanks in part to the deployment of high-tech weapons from NATO, Vladimir Putin has begun to make thinly-veiled threats of deploying his nuclear arsenal in response. No one can be sure how serious he is about this. Most analysts believe that he was referring to the possible use of small-scale tactical nuclear weapons, not a full-scale apocalyptic assault. Many think he’s just bluffing and wouldn’t resort to any nukes at all. Putin has bluffed in the past, and could be doing so again. Honestly, “this is not a bluff” is exactly the sort of thing you say when you’re bluffing—people who aren’t bluffing have better ways of showing it. (It’s like whenever Trump would say “Trust me”, and you’d know immediately that this was an especially good time not to. Of course, any time is a good time not to trust Trump.)

(By the way, financial news is a really weird thing: I actually found this article discussing how a nuclear strike would be disastrous for the economy. Dude, if there’s a nuclear strike, we’ve got much bigger things to worry about than the economy. It reminds me of this XKCD.)

But if Russia did launch nuclear weapons, and NATO responded with its own, it could trigger a nuclear war that would kill millions in a matter of hours. So we need to be prepared, and think very carefully about the best way to respond.

The current debate seems to be over whether to use economic sanctions, conventional military retaliation, or our own nuclear weapons. Well, we already have economic sanctions, and they aren’t making Russia back down. (Though they probably are hurting its war effort, so I’m all for keeping them in place.) And if we were to use our own nuclear weapons, that would only further undermine the global taboo against nuclear weapons and could quite possibly trigger that catastrophic nuclear war. Right now, NATO seems to be going for a bluff of our own: We’ll threaten an overwhelming nuclear response, but then we obviously won’t actually carry it out because that would be murder-suicide on a global scale.

That leaves conventional military retaliation. What sort of retaliation? Several years ago I came up with a very specific method of conventional retaliation I call credible targeted conventional response (CTCR, which you can pronounce “cut-core”). I believe that now would be an excellent time to carry it out.

The basic principle of CTCR is really quite simple: Don’t try to threaten entire nations. A nation is an abstract entity. Threaten people. Decisions are made by people. The response to Vladimir Putin launching nuclear weapons shouldn’t be to kill millions of innocent people in Russia that probably mean even less to Putin than they do to us. It should be to kill Vladimir Putin.

How exactly to carry this out is a matter for military strategists to decide. There are a variety of weapons at our disposal, ranging from the prosaic (covert agents) to the exotic (precision strikes from high-altitude stealth drones). Indeed, I think we should leave it purposefully vague, so that Putin can’t try to defend himself against some particular mode of attack. The whole gamut of conventional military responses should be considered on the table, from a single missile strike to a full-scale invasion.

But the basic goal is quite simple: Launching a nuclear weapon is one of the worst possible war crimes, and it must be met with an absolute commitment to bring the perpetrator to justice. We should be willing to accept some collateral damage, even a lot of collateral damage; carpet-bombing a city shouldn’t be considered out of the question. (If that sounds extreme, consider that we’ve done it before for much weaker reasons.) The only thing that we should absolutely refuse to do is deploy nuclear weapons ourselves.

The great advantage of this strategy—even aside from being obviously more humane than nuclear retaliation—is that it is more credible. It sounds more like something we’d actually be willing to do. And in fact we likely could even get help from insiders in Russia, because there are surely many people in the Russian government who aren’t so loyal to Putin that they’d want him to get away with mass murder. It might not just be an assassination; it might end up turning into a coup. (Also something we’ve done for far weaker reasons.)


This is how we preserve the taboo on nuclear weapons: We refuse to use them, but otherwise stop at nothing to kill anyone who does use them.

I therefore call upon the world to make this threat:

Launch a nuclear weapon, Vladimir Putin, and we will kill you. Not your armies, not your generals—you. It could be a Tomahawk missile at the Kremlin. It could be a car bomb in your limousine, or a Stinger missile at Aircraft One. It could be a sniper at one of your speeches. Or perhaps we’ll poison your drink with polonium, like you do to your enemies. You won’t know when or where. You will live the rest of your short and miserable life in terror. There will be nowhere for you to hide. We will stop at nothing. We will deploy every available resource around the world, and it will be our top priority. And you will die.

That’s how you threaten a psychopath. And it’s what we must do in order to keep the world safe from nuclear war.

Europe is paying the price for relying on Russian natural gas

Sep 18 JDN 2459841

For far too long, Europe has relied upon importing cheap natural gas from Russia to supply a large proportion of its energy needs. Now that the war in Ukraine has led to mutual sanctions, they are paying the price—literally, as the price of natural gas has absolutely ballooned. Dutch natural gas futures have soared from about €15 per megawatt-hour in 2020 to over €200 today.

Natural gas prices are rising worldwide, but not nearly as much: Henry Hub natural gas prices (a standard metric for natural gas prices in the US) have risen from under $2 per million BTU in 2020 to nearly $9 today. This substantial divide in prices can only be sustained because transporting natural gas is expensive and requires substantial infrastructure. (1 megawatt-hour is about 3.4 million BTU, and the euro is trading at parity with the dollar (!), so effectively US prices rose from €7 per MWh to €31 per MWh—as opposed to €200.)

As a result, a lot of people in Europe are suddenly finding their utility bills unaffordable. (I’m fortunate that my flat is relatively well-insulated and my income is reasonably high, so I’m not among them; the higher prices will be annoying, but not beyond my means.) What should we do about this?

There are some economists who would say we should do nothing at all: Laissez-faire. Markets are efficient, right? So just let people freeze! Fortunately, Europe is not governed by such people nearly as much as the US is.

But while most economists would agree that we should do something, it’s much harder to get them to agree on exactly what.

Rising prices of natural gas are sort of a good thing, from an environmental perspective; they’ll provide an incentive to reduce carbon emissions. So it’s tempting to say that we should just let the prices rise and then compensate by raising taxes and paying transfers to poor families. But that probably isn’t politically viable; all three parts—letting prices rise, raising taxes, and increasing transfers—are all going to make enemies, and we really must have all three for such a plan to work.

The current approach seems to be based on price controls: Don’t let the prices rise so much. The UK has such a policy in place: Natural gas prices for consumers are capped by regulations. The cap has been increased in response to the crisis (itself an unpopular, but clearly necessary, move), but even so 31 gas companies have already gone under across the UK since the start of 2021. It really seems to be the case that for many gas companies, especially the smaller ones with less economy of scale, it’s simply not possible to continue providing natural gas to homes with input prices so high and output prices capped so low.

Or, we could let prices rise that high for producers, but subsidize consumers so that they don’t feel it; several European countries are already doing this. That at least won’t result in gas companies failing, but it will cost a lot of government funds. Greece in particular is spending over 3% of their GDP on it! (For comparison, the US military budget is about 4% of GDP.) I think this might actually be the best option, though all that spending will mean more government debt or higher taxes.

European governments have also been building up strategic reserves of natural gas, which may help us get through the winter—but it also makes the current price increases even worse.

We could also ration energy use, as we’ve often done during wartime. (Is this wartime? Kind of? Not really? It certainly is starting to feel like Cold War II.) Indeed, the President of the European Commission basically said that this should happen. That, at least, would reap some of the environmental benefits of reduced natural gas consumption. Rationing also feels fair to most people in a way that simply letting market prices rise does not; there is a sense of shared sacrifice. What worries me, however, is that the rations won’t be well-designed enough to account for energy usage that isn’t in a family’s immediate control. If you’re renting a flat that is poorly insulated, you can’t immediately fix that. You can try to pressure the landlord into buying better insulation, but in the meantime you’re the one paying the energy bills—or getting cold when the natural gas ration isn’t enough.

Actually I strongly suspect that most household usage of natural gas is of this kind; people don’t generally heat their homes more than necessary just because gas is cheap. Maybe they can set the thermostat a degree or two lower when gas is expensive, or maybe they use the gas oven less often and the microwave more; but the vast majority of their gas consumption is a function of the climate they live in and the insulation of their home, not their day-to-day choices. So if we’re trying to incentivize more efficient energy usage, that’s a question of long-term investment in construction and retrofitting, not something that sudden price spikes will really help with.

In the long run, what we really need to do is wean ourselves off of natural gas. Currently natural gas provides 33% of energy and nearly 40% of heating in Europe. (US figures are comparable.) Switching to electric heat pumps and powering them with solar and wind power isn’t something we can do overnight—but it is something we surely must do.

I think ultimately what is going to happen is all of the above: Different countries will adopt different policy mixes, all of them will involve difficult compromises, none of them will be particularly well-designed, and we’ll all sort of muddle through as best we can.

Russia has invaded Ukraine.

Mar 6 JDN 2459645

Russia has invaded Ukraine. No doubt you have heard it by now, as it’s all over the news now in dozens of outlets, from CNN to NBC to The Guardian to Al-Jazeera. And as well it should be, as this is the first time in history that a nuclear power has annexed another country. Yes, nuclear powers have fought wars before—the US just got out of one in Afghanistan as you may recall. They have even started wars and led invasions—the US did that in Iraq. And certainly, countries have been annexing and conquering other countries for millennia. But never before—never before, in human historyhas a nuclear-armed state invaded another country simply to claim it as part of itself. (Trump said he thought the US should have done something like that, and the world was rightly horrified.)

Ukraine is not a nuclear power—not anymore. The Soviet Union built up a great deal of its nuclear production in Ukraine, and in 1991 when Ukraine became independent it still had a sizable nuclear arsenal. But starting in 1994 Ukraine began disarming that arsenal, and now it is gone. Now that Russia has invaded them, the government of Ukraine has begun publicly reconsidering their agreements to disarm their nuclear arsenal.

Russia’s invasion of Ukraine has just disproved the most optimistic models of international relations, which basically said that major power wars for territory were over at the end of WW2. Some thought it was nuclear weapons, others the United Nations, still others a general improvement in trade integration and living standards around the world. But they’ve all turned out to be wrong; maybe such wars are rarer, but they can clearly still happen, because one just did.

I would say that only two major theories of the Long Peace are still left standing in light of this invasion, and that is nuclear deterrence and the democratic peace. Ukraine gave up its nuclear arsenal and later got attacked—that’s consistent with nuclear deterrence. Russia under Putin is nearly as authoritarian as the Soviet Union, and Ukraine is a “hybrid regime” (let’s call it a solid D), so there’s no reason the democratic peace would stop this invasion. But any model which posits that trade or the UN prevent war is pretty much off the table now, as Ukraine had very extensive trade with both Russia and the EU and the UN has been utterly toothless so far. (Maybe we could say the UN prevents wars except those led by permanent Security Council members.)

Well, then, what if the nuclear deterrence theory is right? What would have happened if Ukraine had kept its nuclear weapons? Would that have made this situation better, or worse? It could have made it better, if it acted as a deterrent against Russian aggression. But it could also have made it much, much worse, if it resulted in a nuclear exchange between Russia and Ukraine.

This is the problem with nukes. They are not a guarantee of safety. They are a guarantee of fat tails. To explain what I mean by that, let’s take a brief detour into statistics.

A fat-tailed distribution is one for which very extreme events have non-negligible probability. For some distributions, like a uniform distribution, events are clearly contained within a certain interval and nothing outside is even possible. For others, like a normal distribution or lognormal distribution, extreme events are theoretically possible, but so vanishingly improbable they aren’t worth worrying about. But for fat-tailed distributions like a Cauchy distribution or a Pareto distribution, extreme events are not so improbable. They may be unlikely, but they are not so unlikely they can simply be ignored. Indeed, they can actually dominate the average—most of what happens, happens in a handful of extreme events.

Deaths in war seem to be fat-tailed, even in conventional warfare. They seem to follow a Pareto distribution. There are lots of tiny skirmishes, relatively frequent regional conflicts, occasional major wars, and a handful of super-deadly global wars. This kind of pattern tends to emerge when a phenomenon is self-reinforcing by positive feedback—hence why we also see it in distributions of income and wildfire intensity.

Fat-tailed distributions typically (though not always—it’s easy to construct counterexamples, like the Cauchy distribution with low values truncated off) have another property as well, which is that minor events are common. More common, in fact, than they would be under a normal distribution. What seems to happen is that the probability mass moves away from the moderate outcomes and shifts to both the extreme outcomes and the minor ones.

Nuclear weapons fit this pattern perfectly. They may in fact reduce the probability of moderate, regional conflicts, in favor of increasing the probability of tiny skirmishes or peaceful negotiations. But they also increase the probability of utterly catastrophic outcomes—a full-scale nuclear war could kill billions of people. It probably wouldn’t wipe out all of humanity, and more recent analyses suggest that a catastrophic “nuclear winter” is unlikely. But even 2 billion people dead would be literally the worst thing that has ever happened, and nukes could make it happen in hours when such a death toll by conventional weapons would take years.

If we could somehow guarantee that such an outcome would never occur, then the lower rate of moderate conflicts nuclear weapons provide would justify their existence. But we can’t. It hasn’t happened yet, but it doesn’t have to happen often to be terrible. Really, just once would be bad enough.

Let us hope, then, that the democratic peace turns out to be the theory that’s right. Because a more democratic world would clearly be better—while a more nuclearized world could be better, but could also be much, much worse.

The extreme efficiency of environmental regulation—and the extreme inefficiency of war

Apr 8 JDN 2458217

Insofar as there has been any coherent policy strategy for the Trump administration, it has largely involved three things:

  1. Increase investment in military, incarceration, and immigration enforcement
  2. Redistribute wealth from the poor and middle class to the rich
  3. Remove regulations that affect business, particularly environmental regulations

The human cost of such a policy strategy is difficult to overstate. Literally millions of people will die around the world if such policies continue. This is almost the exact opposite of what our government should be doing.

This is because military is one of the most wasteful and destructive forms of government investment, while environmental regulation is one of the most efficient and beneficial. The magnitude of these differences is staggering.

First of all, it is not clear that the majority of US military spending provides any marginal benefit. It could quite literally be zero. The US spends more on military than the next ten countries combined.

I think it’s quite reasonable to say that the additional defense benefit becomes negligible once you exceed the sum of spending from all plausible enemies. China, Russia, and Saudi Arabia together add up to about $350 billion per year. Current US spending is $610 billion per year. (And this calculation, by the way, requires them all to band together, while simultaneously all our NATO allies completely abandon us.) That means we could probably cut $260 billion per year without losing anything.

What about the remaining $350 billion? I could be extremely generous here, and assume that nuclear weapons, alliances, economic ties, and diplomacy all have absolutely no effect, so that without our military spending we would be invaded and immediately lose, and that if we did lose a war with China or Russia it would be utterly catastrophic and result in the deaths of 10% of the US population. Since in this hypothetical scenario we are only preventing the war by the barest margin, each year of spending only adds 1 year to the lives of the war’s potential victims. That means we are paying some $350 billion per year to add 1 year to the lives of 32 million people. That is a cost of about $11,000 per QALY. If it really is saving us from being invaded, that doesn’t sound all that unreasonable. And indeed, I don’t favor eliminating all military spending.

Of course, the marginal benefit of additional spending is still negligible—and UN peacekeeping is about twice as cost-effective as US military action, even if we had to foot the entire bill ourselves.

Alternatively, I could consider only the actual, documented results of our recent military action, which has resulted in over 280,000 deaths in Iraq and 110,000 in Afghanistan, all for little or no apparent gain. Life expectancy in these countries is about 70 in Iraq and 60 in Afghanistan. Quality of life there is pretty awful, but people are also greatly harmed by war without actually dying in it, so I think a fair conversion factor is about 60 QALY per death. That’s a loss of 23.4 MQALY. The cost of the Iraq War was about $1.1 trillion, while the cost of the Afghanistan War was about a further $1.1 trillion. This means that we paid $94,000 per lost QALY. If this is right, we paid enormous amounts to destroy lives and accomplished nothing at all.

Somewhere in between, we could assume that cutting the military budget greatly would result in the US being harmed in a manner similar to World War 2, which killed about 500,000 Americans. Paying $350 billion per year to gain 500,000 QALY per year is a price of $700,000 per QALY. I think this is about right; we are getting some benefit, but we are spending an enormous amount to get it.

Now let’s compare that to the cost-effectiveness of environmental regulation.

Since 1990, the total cost of implementing the regulations in the Clean Air Act was about $65 billion. That’s over 28 years, so less than $2.5 billion per year. Compare that to the $610 billion per year we spend on the military.

Yet the Clean Air Act saves over 160,000 lives every single year. And these aren’t lives extended one more year as they were in the hypothetical scenario where we are just barely preventing a catastrophic war; most of these people are old, but go on to live another 20 years or more. That means we are gaining 3.2 MQALY for a price of $2.5 billion. This is a price of only $800 per QALY.

From 1970 to 1990, the Clean Air Act cost more to implement: about $520 billion (so, you know, less than one year of military spending). But its estimated benefit was to save over 180,000 lives per year, and its estimated economic benefit was $22 trillion.

Look at those figures again, please. Even under very pessimistic assumptions where we would be on the verge of war if not for our enormous spending, we’re spending at least $11,000 and probably more like $700,000 on the military for each QALY gained. But environmental regulation only costs us about $800 per QALY. That’s a factor of at least 14 and more likely 1000. Environmental regulation is probably about one thousand times as cost-effective as military spending.

And I haven’t even included the fact that there is a direct substitution here: Climate change is predicted to trigger thousands if not millions of deaths due to military conflict. Even if national security were literally the only thing we cared about, it would probably still be more cost-effective to invest in carbon emission reduction rather than building yet another aircraft carrier. And if, like me, you think that a child who dies from asthma is just as important as one who gets bombed by China, then the cost-benefit analysis is absolutely overwhelming; every $60,000 spent on war instead of environmental protection is a statistical murder.

This is not even particularly controversial among economists. There is disagreement about specific environmental regulations, but the general benefits of fighting climate change and keeping air and water clean are universally acknowledged. There is disagreement about exactly how much military spending is necessary, but you’d be hard-pressed to find an economist who doesn’t think we could cut our military substantially with little or no risk to security.

And so begins the trade war Trump promised us.

Mar 18 JDN 2458196

President Trump (a phrase I will never quite feel comfortable saying) has used an obscure loophole in US trade law to impose huge tariffs on steel and aluminum. The loophole is based on the idea that certain goods are vital for national security, and therefore imposing tariffs on them is in some sense the proper role of the Commander in Chief. It’s a pretty flimsy justification in general (if it’s really so important, why can’t Congress do it?), and particularly so in this case: Most of our steel and aluminum comes from Canada, and we are still totally dependent on imports for bauxite to make aluminum. Trump did finally cave in on allowing NAFTA members to be exempt, so Canada won’t be paying the tariff. The only country that could plausibly be considered an enemy that will be meaningfully affected by the tariffs is (ironically) Russia.

The European Union has threatened to respond with their own comparable tariffs—meaning that a trade war has officially begun. The last time the US started a major trade war was in 1930—which you may recognize as the start of the Great Depression. There’s a meme going around saying that 1928 was the last time the Republican Party controlled the whole US government; that isn’t actually true. Republicans have controlled all three branches as recently as 2006. Of course, the late 2000s weren’t a great time for the US economy either, so make of that what you will.

Does this mean we’re headed toward another Great Depression? I don’t think so. Our monetary policy is vastly better now than it was then. But are we headed toward another recession? That seems quite likely. By standard measures, the stock market is overvalued. The unemployment rate is now at 4%. We are basically at the ceiling right now; the only place to go is down.

Of course, maybe we will stay here awhile. We don’t have to go down, necessarily. If Obama were still President and Yellen were still Fed Chair, I might believe that. But the level of corruption, incompetence, and ideological rigidity in Trump’s economic policy is something I’ve not seen in the United States within my lifetime.

Peter Navarro, Trump’s Director of the White House Trade Council, has described his own role in an incredibly chilling way:

“This is the president’s vision. My function, really, as an economist is to try to provide the underlying analytics that confirm his intuition. And his intuition is always right in these matters. […] The owner, the coach, and the quarterback are all the president. The rest of us are all interchangeable parts.”

Well, there you have it. It’s just as the saying goes: There are liberal professional economists, conservative professional economists, and professional conservative economists. Peter Navarro has officially and proudly declared himself a professional conservative economist. He seems proud to admit that his only function is to rationalize what Trump already believes.

We really shouldn’t be surprised that Trump brought us into a trade war. Frankly, it was one of his campaign promises. When he was announcing the tariffs, he declared, “Trade wars are good, and easy to win.” In fact, trade war is much like real war, in that the only winning move is not to play.

What really worries me about all this isn’t how it will affect the US. Maybe it’ll trigger another recession, sure; but we’ve had lots of those, and we make it through eventually. (Recession might even be good for our carbon emissions, as we’re well above the Wedge.) The US economy is very strong, and can withstand a lot of mistakes. Even on a bad day we’re still the richest country in the world.

What worries me is how it will affect other countries. It’ll start with countries that export steel and aluminum, like India, China and Brazil. But as tariffs and counter-tariffs proliferate, more and more exports will be brought into the trade war. Trade is one of the most powerful tools we have for fighting global poverty, and we are now pulling the plug.

Of course, hurting China was part of Trump’s goal, so I doubt he’ll feel much remorse if the trade war results in millions of people in China thrown back into poverty. People who voted for him on the grounds that he would keep the dirty foreigners down may well be celebrating such an outcome.

There will be pain. But most of it will be felt elsewhere from here. “But those were Foreign children and it didn’t really matter.”

How rich are we, really?

Oct 29, JDN 2458056

The most commonly-used measure of a nation’s wealth is its per-capita GDP, which is simply a total of all spending in a country divided by its population. More recently we adjust for purchasing power, giving us GDP per capita at purchasing power parity (PPP).

By this measure, the United States always does well. At most a dozen countries are above us, most of them by a small amount, and all of them are quite small countries. (For fundamental statistical reasons, we should expect both the highest and lowest average incomes to be in the smallest countries.)

But this is only half the story: It tells us how much income a country has, but not how that income is distributed. We should adjust for inequality.

How can we do this? I have devised a method that uses the marginal utility of wealth plus a measure of inequality called the Gini coefficient to work out an estimate of the average utility, instead of the average income.

I then convert back into a dollar figure. This figure is the income everyone would need to have under perfect equality, in order to give the same real welfare as the current system. That is, if we could redistribute wealth in such a way to raise everyone above this value up to it, and lower everyone above this value down to it, the total welfare of the country would not change. This provides a well-founded ranking of which country’s people are actually better off overall, accounting for both overall income and the distribution of that income.

The estimate is sensitive to the precise form I use for marginal utility, so I’ll show you comparisons for three different cases.

The “conservative” estimate uses a risk aversion parameter of 1, which means that utility is logarithmic in income. The real value of a dollar is inversely proportional to the number of dollars you already have.

The medium estimate uses a risk aversion parameter of 2, which means that the real value of a dollar is inversely proportional to the square of the number of dollars you already have.

And then the “liberal” estimate uses a risk aversion parameter of 3, which means that the real value of a dollar is inversely proportional to the cube of the number of dollars you already have.

I’ll compare ten countries, which I think are broadly representative of classes of countries in the world today.

The United States, the world hegemon which needs no introduction.

China, rising world superpower and world’s most populous country.

India, world’s largest democracy and developing economy with a long way to go.

Norway, as representative of the Scandinavian social democracies.

Germany, as representative of continental Europe.

Russia, as representative of the Soviet Union and the Second World bloc.

Saudi Arabia, as representative of the Middle East petrostates.

Botswana, as representative of African developing economies.

Zimbabwe, as representative of failed Sub-Saharan African states.

Brazil, as representative of Latin American developing economies.
The ordering of these countries by GDP per-capita PPP is probably not too surprising:

  1. Norway 69,249
  2. United States 57,436
  3. Saudi Arabia 55,158
  4. Germany 48,111
  5. Russia 26,490
  6. Botswana 17,042
  7. China 15,399
  8. Brazil 15,242
  9. India 6,616
  10. Zimbabwe 1,970

Norway is clearly the richest, the US, Saudi Arabia, and Germany are quite close, Russia is toward the upper end, Botswana, China, and Brazil are close together in the middle, and then India and especially Zimbabwe are extremely poor.

But now let’s take a look at the inequality in each country, as measured by the Gini coefficient (which ranges from 0, perfect equality, to 1, total inequality).

  1. Botswana 0.605
  2. Zimbabwe 0.501
  3. Brazil 0.484
  4. United States 0.461
  5. Saudi Arabia 0.459
  6. China 0.422
  7. Russia 0.416
  8. India 0.351
  9. Germany 0.301
  10. Norway 0.259

The US remains (alarmingly) close to Saudi Arabia by this measure. Most of the countries are between 40 and 50. But Botswana is astonishingly unequal, while Germany and Norway are much more equal.

With that in mind, let’s take a look at the inequality-adjusted per-capita GDP. First, the conservative estimate, with a parameter of 1:

  1. Norway 58700
  2. United States 42246
  3. Saudi Arabia 40632
  4. Germany 39653
  5. Russia 20488
  6. China 11660
  7. Botswana 11138
  8. Brazil 11015
  9. India 5269
  10. Zimbabwe 1405

So far, ordering of nations is almost the same compared to what we got with just per-capita GDP. But notice how Germany has moved up closer to the US and Botswana actually fallen behind China.

Now let’s try a parameter of 2, which I think is the closest to the truth:

  1. Norway 49758
  2. Germany 32683
  3. United States 31073
  4. Saudi Arabia 29931
  5. Russia 15581
  6. China 8829
  7. Brazil 7961
  8. Botswana 7280
  9. India 4197
  10. Zimbabwe 1002

Now we have seen some movement. Norway remains solidly on top, but Germany has overtaken the United States and Botswana has fallen behind not only China, but also Brazil. Russia remains in the middle, and India and Zimbawbe remain on the bottom.

Finally, let’s try a parameter of 3.

  1. Norway 42179
  2. Germany 26937
  3. United States 22855
  4. Saudi Arabia 22049
  5. Russia 11849
  6. China 6685
  7. Brazil 5753
  8. Botswana 4758
  9. India 3343
  10. Zimbabwe 715

Norway has now pulled far and away ahead of everyone else. Germany is substantially above the United States. China has pulled away from Brazil, and Botswana has fallen almost all the way to the level of India. Zimbabwe, as always, is at the very bottom.

Let’s compare this to another measure of national well-being, the Inequality-Adjusted Human Development Index (which goes from 0, the worst, to 1 the best). This index combines education, public health, and income, and adjusts for inequality. It seems to be a fairly good measure of well-being, but it’s very difficult to compile data for, so a lot of countries are missing (including Saudi Arabia); plus the precise weightings on everything are very ad hoc.

  1. Norway 0.898
  2. Germany 0.859
  3. United States 0.796
  4. Russia 0.725
  5. China 0.543
  6. Brazil 0.531
  7. India 0.435
  8. Botswana 0.433
  9. Zimbabwe 0.371

Other than putting India above Botswana, this ordering is the same as what we get from my (much easier to calculate and theoretically more well-founded) index with either a parameter of 2 or 3.

What’s more, my index can be directly interpreted: The average standard of living in the US is as if everyone were making $31,073 per year. What exactly is an IHDI index of 0.796 supposed to mean? We’re… 79.6% of the way to the best possible country?

In any case, there’s a straightforward (if not terribly surprising) policy implication here: Inequality is a big problem.

In particular, inequality in the US is clearly too high. Despite an overall income that is very high, almost 18 log points higher than Germany, our overall standard of living is actually about 5 log points lower due to our higher level of inequality. While our average income is only 19 log points lower than Norway, our actual standard of living is 47 log points lower.

Inequality in Botswana also means that their recent astonishing economic growth is not quite as impressive as it at first appeared. Many people are being left behind. While in raw income they appear to be 10 log points ahead of China and only 121 log points behind the US, once you adjust for their very high inequality they are 19 log points behind China, and 145 log points behind the US.

Of course, some things don’t change. Norway is still on top, and Zimbabwe is still on the bottom.

What is the point of democracy?

Apr 9, JDN 2457853

[This topic was chosen by Patreon vote.]

“Democracy” is the sort of word that often becomes just an Applause Light (indeed it was the original example Less Wrong used). Like “freedom” and “liberty” (and for much the same reasons), it’s a good thing, that much we know; but it’s often unclear what is even meant by the word, much less why it should be so important to us.

From another angle, it is strangely common for economists and political scientists to argue that democracy is not all that important; they at least tend to use a precise formal definition of “democracy”, but are oddly quick to dismiss it as pointless or even harmful when it doesn’t line up precisely with their models of an efficient economy or society. I think the best example of this is the so-called “Downs paradox”, where political scientists were so steeped in the tradition of defining all rationality as psychopathic self-interest that they couldn’t even explain why it would occur to anyone to vote. (And indeed, rumor has it that most economists don’t bother to vote, much less campaign politically—which perhaps begins to explain why our economic policy is so terrible.)

Yet especially for Americans in the Trump era, I think it is vital to understand what “democracy” is supposed to mean, and why it is so important.

So, first of all, what is democracy? It is nothing more or less than government by popular vote.

This comes in degrees, of course: The purest direct democracy would have the entire population vote on even the most mundane policies and decisions. You could actually manage something like a monastery or a social club in such a fashion, but this is clearly unworkable on any large scale. Even once you get to hundreds of people, much less thousands or millions, it becomes unviable. The closest example I’ve seen is Switzerland, where there are always numerous popular referenda on ballots that are voted on by entire regions or the entire country—and even then, Switzerland does have representatives that make many of the day-to-day decisions.

So in practice all large-scale democratic systems are some degree of representative democracy, or republic, where some especially decisions may be made by popular vote, but most policies are made by elected representatives, staff appointed by those representatives, or even career civil servants who are appointed in a nominally apolitical process not so different from private-sector hiring. In the most extreme cases such civil servants can become so powerful that you get a deep state, where career bureaucrats exercise more power than elected officials—at that point I think you have actually lost the right to really call yourself a “democracy” and have become something more like a technocracy.
Yet of course a country can get even more undemocratic than that, and many are, governed by an aristocracy or oligarchy that vests power in a small number of wealthy and powerful individuals, or monarchy or autocracy that gives near-absolute power to a single individual.

Thus, there is a continuum of most to least democratic, with popular vote at one end, followed by elected representatives, followed by appointed civil servants, followed by a handful of oligarchs, and ultimately the most undemocratic system is an autocracy controlled by a single individual.

I also think it’s worth mentioning that constitutional monarchies with strong parliamentary systems, like the United Kingdom and Norway, are also “democracies” in the sense I intend. Yes, technically they have these hereditary monarchs—but in practice, the vast majority of the state’s power is vested in the votes of its people. Indeed, if we separate out parliamentary constitutional monarchy from presidential majoritarian democracy and compare them, the former might actually turn out to be better. Certainly, some of the world’s most prosperous nations are governed that way.

As I’ve already acknowledge, the very far extreme of pure direct democracy is unfeasible. But why would we want to get closer to that end? Why be like Switzerland or Denmark rather than like Turkey or Russia—or for that matter why be like California rather than like Mississippi?
Well, if you know anything about the overall welfare of these states, it almost seems obvious—Switzerland and Denmark are richer, happier, safer, healthier, more peaceful, and overall better in almost every way than Turkey and Russia. The gap between California and Mississippi is not as large, but it is larger than most people realize. Median household income in California is $64,500; in Mississippi it is only $40,593. Both are still well within the normal range of a highly-developed country, but that effectively makes California richer than Luxembourg but Mississippi poorer than South Korea. But perhaps the really stark comparison to make is life expectancy: Life expectancy at birth in California is almost 81 years, while in Mississippi it’s only 75.

Of course, there are a lot of other differences between states besides how much of their governance is done by popular referendum. Simply making Mississippi decide more things by popular vote would not turn it into California—much less would making Turkey more democratic turn it into Switzerland. So we shouldn’t attribute these comparisons entirely to differences in democracy. Indeed, a pair of two-way comparisons is only in the barest sense a statistical argument; we should be looking at dozens if not hundreds of comparisons if we really want to see the effects of democracy. And we should of course be trying to control for other factors, adjust for country fixed-effects, and preferably use natural experiments or instrumental variables to tease out causality.

Yet such studies have in fact been done. Stronger degrees of democracy appear to improve long-run economic growth, as well as reduce corruption, increase free trade, protect peace, and even improve air quality.

Subtler analyses have compared majoritarian versus proportional systems (where proportional seems, to me, at least, more democratic), as well as different republican systems with stronger or weaker checks and balances (stronger is clearly better, though whether that is “more democratic” is at least debatable). The effects of democracy on income distribution are more complicated, probably because there have been some highly undemocratic socialist regimes.

So, the common belief that democracy is good seems to be pretty well supported by the data. But why is democracy good? Is it just a practical matter of happening to get better overall results? Could it one day be overturned by some superior system such as technocracy or a benevolent autocratic AI?

Well, I don’t want to rule out the possibility of improving upon existing systems of government. Clearly new systems of government have in fact emerged over the course of history—Greek “democracy” and Roman “republic” were both really aristocracy, and anything close to universal suffrage didn’t really emerge on a large scale until the 20th century. So the 21st (or 22nd) century could well devise a superior form of government we haven’t yet imagined.
However, I do think there is good reason to believe that any new system of government that actually manages to improve upon democracy will still resemble democracy, because there are three key features democracy has that other systems of government simply can’t match. It is these three features that make democracy so important and so worth fighting for.

1. Everyone’s interests are equally represented.

Perhaps no real system actually manages to represent everyone’s interests equally, but the more democratic a system is, the better it will conform to this ideal. A well-designed voting system can aggregate the interests of an entire population and choose the course of action that creates the greatest overall benefit.

Markets can also be a good system for allocating resources, but while markets represent everyone’s interests, they do so highly unequally. Rich people are quite literally weighted more heavily in the sum.

Most systems of government do even worse, by completely silencing the voices of the majority of the population. The notion of a “benevolent autocracy” is really a conceit; what makes you think you could possibly keep the autocrat benevolent?

This is also why any form of disenfranchisement is dangerous and a direct attack upon democracy. Even if people are voting irrationally, against their own interests and yours, by silencing their voice you are undermining the most fundamental tenet of democracy itself. All voices must be heard, no exceptions. That is democracy’s fundamental strength.

2. The system is self-correcting.

This may more accurately describe a constitutional republican system with strong checks and balances, but that is what most well-functioning democracies have and it is what I recommend. If you conceive of “more democracy” as meaning that people can vote their way into fascism by electing a sufficiently charismatic totalitarian, then I do not want us to have “more democracy”. But just as contracts and regulations that protect you can make you in real terms more free because you can now safely do things you otherwise couldn’t risk, I consider strong checks and balances that maintain the stability of a republic against charismatic fascists to be in a deeper sense more democratic. This is ultimately semantic; I think I’ve made it clear enough that I want strong checks and balances.

With such checks and balances in place, democracies may move slower than autocracies; they may spend more time in deliberation or even bitter, polarized conflict. But this also means that their policies do not lurch from one emperor’s whim to another, and they are stable against being overtaken by corruption or fascism. Their policies are stable and predictable; their institutions are strong and resilient.

No other system of government yet devised by humans has this kind of stability, which may be why democracies are gradually taking over the world. Charismatic fascism fails when the charismatic leader dies; hereditary monarchy collapses when the great-grandson of the great king is incompetent; even oligarchy and aristocracy, which have at least some staying power, ultimately fall apart when the downtrodden peasants ultimately revolt. But democracy abides, for where monarchy and aristocracy are made of families and autocracy and fascism are made of a single man, democracy is made of principles and institutions. Democracy is evolutionarily stable, and thus in Darwinian terms we can predict it will eventually prevail.

3. The coercion that government requires is justified.

All government is inherently coercive. Libertarians are not wrong about this. Taxation is coercive. Regulation is coercive. Law is coercive. (The ones who go on to say that all government is “death threats” or “slavery” are bonkers, mind you. But it is in fact coercive.)

The coercion of government is particularly terrible if that coercion is coming from a system like an autocracy, where the will of the people is minimally if at all represented in the decisions of policymakers. Then that is a coercion imposed from outside, a coercion in the fullest sense, one person who imposes their will upon another.

But when government coercion comes from a democracy, it takes on a fundamentally different meaning. Then it is not they who coerce us—it is we who coerce ourselves. Now, why in the world would you coerce yourself? It seems ridiculous, doesn’t it?

Not if you know any game theory. There are in fall all sorts of reasons why one might want to coerce oneself, and two in particular become particularly important for the justification of democratic government.

The first and most important is collective action: There are many situations in which people all working together to accomplish a goal can be beneficial to everyone, but nonetheless any individual person who found a way to shirk their duty and not contribute could benefit even more. Anyone who has done a group project in school with a couple of lazy students in it will know this experience: You end up doing all the work, but they still get a good grade at the end. If everyone had taken the rational, self-interested action of slacking off, everyone in the group would have failed the project.

Now imagine that the group project we’re trying to achieve is, say, defending against an attack by Imperial Japan. We can’t exactly afford to risk that project falling through. So maybe we should actually force people to support it—in the form of taxes, or even perhaps a draft (as ultimately we did in WW2). Then it is no longer rational to try to shirk your duty, so everyone does their duty, the project gets done, and we’re all better off. How do we decide which projects are important enough to justify such coercion? We vote, of course. This is the most fundamental justification of democratic government.

The second that is relevant for government is commitment. There are many circumstances in which we want to accomplish something in the future, and from a long-run perspective it makes sense to achieve that goal—but then when the time comes to take action, we are tempted to procrastinate or change our minds. How can we resolve such a dilemma? Well, one way is to tie our own hands—to coerce ourselves into carrying out the necessary task we are tempted to avoid or delay.

This applies to many types of civil and criminal law, particularly regarding property ownership. Murder is a crime that most people would not commit even if it were completely legal. But shoplifting? I think if most people knew there would be no penalty for petty theft and retail fraud they would be tempted into doing it at least on occasion. I doubt it would be frequent enough to collapse our entire economic system, but it would introduce a lot of inefficiency, and make almost everything more expensive. By having laws in place that punish us for such behavior, we have a way of defusing such temptations, at least for most people most of the time. This is not as important for the basic functioning of government as is collective action, but I think it is still important enough to be worthy of mention.

Of course, there will always be someone who disagrees with any given law, regardless of how sensible and well-founded that law may be. And while in some sense “we all” agreed to pay these taxes, when the IRS actually demands that specific dollar amount from you, it may well be an amount that you would not have chosen if you’d been able to set our entire tax system yourself. But this is a problem of aggregation that I think may be completely intractable; there’s no way to govern by consensus, because human beings just can’t achieve consensus on the scale of millions of people. Governing by popular vote and representation is the best alternative we’ve been able to come up with. If and when someone devises a system of government that solves that problem and represents the public will even better than voting, then we will have a superior alternative to democracy.

Until then, it is as Churchill said: “Democracy is the worst form of government, except for all the others.”
