Alien invasions: Could they happen, and could we survive?

It’s not actually the top-grossing film in the US right now (that would be The Secret Life of Pets), but Independence Day: Resurgence made a quite respectable gross of $343 million worldwide, giving it an ROI of 108% over its budget of $165 million. It speaks to something deep in our minds—and since most of the money came from outside the US, apparently not just Americans, though it is a deeply American film—about the fear, but perhaps also the excitement, of a possible alien invasion.

So, how likely are alien invasions anyway?

Well, first of all, how likely are aliens?

One of the great mysteries of astronomy is the Fermi Paradox: Everything we know about astronomy, biology, and probability tells us that there should be, somewhere out in the cosmos, a multitude of extraterrestrial species, and some of them should even be intelligent enough to form civilizations and invent technology. So why haven’t we found any clear evidence of any of them?

Indeed, the Fermi Paradox became even more baffling in just the last two years, as we found literally thousands of new extrasolar planets, many of them quite likely to be habitable. More extrasolar planets have been found since 2014 than in all previous years of human civilization. Perhaps this is less surprising when we remember that no extrasolar planets had ever been confirmed before 1992—but personally I think that just makes it this much more amazing that we are lucky enough to live in such a golden age of astronomy.

The Drake equation was supposed to tell us how probable it is that we should encounter an alien civilization, but the equation isn’t much use to us because so many of its terms are so wildly uncertain. Maybe we can pin down how many planets there are soon, but we still don’t know what proportion of planets can support life, what proportion of those actually have life, or above all what proportion of ecosystems ever manage to evolve a technological civilization or how long such a civilization is likely to last. All possibilities from “they’re everywhere but we just don’t notice or they actively hide from us” to “we are actually the only ones in the last million years” remain on the table.

But let’s suppose that aliens do exist, and indeed have technology sufficient to reach our solar system. Faster-than-light capability would certainly do it, but it isn’t strictly necessary; with long lifespans, cryonic hibernation, or relativistic propulsion aliens could reasonably expect to travel at least between nearby stars within their lifetimes. The Independence Day aliens appear to have FTL travel, but interestingly it makes the most sense if they do not have FTL communication—it took them 20 years to get the distress call because it was sent at lightspeed. (Or perhaps the ansible was damaged in the war, and they fell back to a lightspeed emergency system?) Otherwise I don’t quite get why it would take the Queen 20 years to deploy her personal battlecruiser after the expeditionary force she sent was destroyed—maybe she was just too busy elsewhere to bother with our backwater planet? What did she want from our planet again?

That brings me to my next point: Just what motivation would aliens have for attacking us? We often take it for granted that if aliens exist, and have the capability to attack us, they would do so. But that really doesn’t make much sense. Do they just enjoy bombarding primitive planets? I guess it’s possible they’re all sadistic psychopaths, but it seems like any civilization stable enough to invent interstellar travel has got to have some kind of ethical norms. Maybe they see us as savages or even animals, and are therefore willing to kill us—but that still means they need a reason.

Another idea, taken seriously in V and less so in Cowboys & Aliens, is that there is some sort of resource we have that they want, and they’re willing to kill us to get it. This is probably such a common trope because it has been a common part of human existence; we are very familiar with people killing other people in order to secure natural resources such as gold, spices, or oil. (Indeed, to some extent it continues to this day.)

But this actually doesn’t make a lot of sense on an interstellar scale. Certainly water (V) and gold (Cowboys & Aliens) are not things they would have even the slightest reason to try to claim from an inhabited planet, as comets are a better source of water and asteroids are a better source of gold. Indeed, almost nothing inorganic could really be cost-effective to obtain from an inhabited planet; far easier to just grab it from somewhere that won’t fight back, and may even have richer veins and lower gravity.

It’s possible they would want something organic—lumber or spices, I guess. But I’m not sure why they’d want those things, and it seems kind of baffling that they wouldn’t just trade if they really want them. I’m sure we’d gladly give up a great deal of oregano and white pine in exchange for nanotechnology and FTL. I guess I could see this happening because they assume we’re too stupid to be worth trading with, or they can’t establish reliable means of communication. But one of the reasons why globalization has succeeded where colonialism failed is that trade is a lot more efficient than theft, and I find it unlikely that aliens this advanced would have failed to learn that lesson.

Media that imagines they’d enslave us makes even less sense; slavery is wildly inefficient, and they probably have such ludicrously high productivity that they are already coping with a massive labor glut. (I suppose maybe they send off unemployed youths to go conquer random planets just to give them something to do with their time? Helps with overpopulation too.)

I actually thought Independence Day: Resurgence did a fairlygood job of finding a resource that is scarce enough to be worth fighting over while also not being something we would willingly trade. Spoiler alert, I suppose:

Molten cores. Now, I haven’t the foggiest what one does with molten planet cores that somehow justifies the expenditure of all that energy flying between solar systems and digging halfway through planets with gigantic plasma drills, but hey, maybe they are actually tremendously useful somehow. They certainly do contain huge amounts of energy, provided you can extract it efficiently. Moreover, they are scarce; of planets we know about, most of them do not have molten cores. Earth, Venus, and Mercury do, and we think Mars once did; but none of the gas giants do, and even if they did, it’s quite plausible that the Queen’s planet-cracker drill just can’t drill that far down. Venus sounds like a nightmare to drill, so really the only planet I’d expect them to extract before Earth would be Mercury. And maybe they figured they needed both cores to justify the trip, in which case it would make sense to hit the inhabited planet first so we don’t have time to react and prepare our defenses. (I can’t imagine we’d take giant alien ships showing up and draining Mercury’s core lying down.) I’m imagining the alien economist right now, working out the cost-benefit analysis of dealing with Venus’s superheated atmosphere and sulfuric acid clouds compared to the cost of winning a war against primitive indigenous apes with nuclear missiles: Well, doubling our shield capacity is cheaper than covering the whole ship in sufficient anticorrosive, so I guess we’ll go hit the ape planet. (They established in the first film that their shields can withstand direct hits from nukes—the aliens came prepared.)

So, maybe killing us for our resources isn’t completely out of the question, but it seems unlikely.

Another possibility is religious fanaticism: Every human culture has religion in some form, so why shouldn’t the aliens? And if they do, it’s likely radically different from anything we believe. If they become convinced that our beliefs are not simply a minor nuisance but an active threat to the holy purity of the galaxy, they could come to our system on a mission to convert or destroy at any cost; and since “convert” seems very unlikely, “destroy” would probably become their objective pretty quickly. It wouldn’t have to make sense in terms of a cost-benefit analysis—fanaticism doesn’t have to make sense at all. The good news here is that any culture fanatical enough to randomly attack other planets simply for believing differently from them probably won’t be cohesive enough to reach that level of technology. (Then again, we somehow managed a world with both ISIS and ICBMs.)

Personally I think there is a far more likely scenario for alien invasions, and that is benevolent imperialism.

Why do I specify “benevolent”? Because if they aren’t interested in helping us, there’s really no reason for them to bother with us in the first place. But if their goal is to uplift our civilization, the only way they can do that is by interacting with us.

Now, note that I use the word “benevolent”, not the word “beneficent”. I think they would have to desire to make our lives better—but I’m not so convinced they actually would make our lives better. In our own history, human imperialism was rarely benevolent in the first place, but even where it was, it was even more rarely actually beneficent. Their culture would most likely be radically different from our own, and what they think of as improvements might seem to us strange, pointless, or even actively detrimental. But don’t you see that the QLX coefficient is maximized if you convert all your mountains into selenium extractors? (This is probably more or less how Native Americans felt when Europeans started despoiling their land for things called “coal” and “money”.) They might even try to alter us biologically to be more similar to them: But haven’t you always wanted tentacles? Hands are so inefficient!

Moreover, even if their intentions were good and their methods of achieving them were sound, it’s still quite likely that we would violently resist. I don’t know if humans are a uniquely rebellious species—let’s hope not, lest the aliens be shocked into overreacting when we rebel—but in general humans do not like being ruled over and forced to do things, even when those rulers are benevolent and the things they are forced to do are worth doing.

So, I think the most likely scenario for a war between humans and aliens is that they come in and start trying to radically reorganize our society, and either because their demands actually are unreasonable, or at least because we think they are, we rebel against their control.

Then what? Could we actually survive?

The good news is: Yes, we probably could.

If aliens really did come down trying to extract our molten core or something, the movies are all wrong: We’d have basically no hope. It really makes no sense at all that we could win a full-scale conflict with a technologically superior species if they were willing to exterminate us. Indeed, if what they were after didn’t depend upon preserving local ecology, their most likely mode of attack is to arrive in the system and immediately glass the planet. Nuclear weapons are already available to us for that task; if they’re more advanced they might have antimatter bombs, relativistic kinetic warheads, or even something more powerful still. We might be all dead before we even realized what was happening, or they might destroy 90% of us right away and mop up the survivors later with little difficulty.

If they wanted something that required ecological stability (I shall henceforth dub this the “oregano scenario”), yet weren’t willing to trade for some reason, then they wouldn’t unleash full devastation, and we’d have the life-dinner principle on our side: The hare runs for his life, but the fox only runs for her dinner. So if the aliens are trying to destroy us to get our delicious spices, we have a certain advantage from the fact that we are willing to win at essentially any cost, while at some point that alien economist is going to run the numbers and say, “This isn’t cost-effective. Let’s cut our losses and hit another system instead.”

If they wanted to convert us to their religion, well, we’d better hope enough people convert, because otherwise they’re going to revert to, you guessed it, glass the planet. At least this means they would probably at least try to communicate first, so we’d have some time to prepare; but it’s unlikely that even if their missionaries spent decades trying to convert us we could seriously reduce our disadvantage in military technology during that time. So really, our best bet is to adopt the alien religion. I guess what I’m really trying to say here is “All Hail Xemu.”

But in the most likely scenario that their goal is actually to make our lives better, or at least better as they see it, they will not be willing to utilize their full military capability against us. They might use some lethal force, especially if they haven’t found reliable means of nonlethal force on sufficient scale; but they aren’t going to try to slaughter us outright. Maybe they kill a few dissenters to set an example, or fire into a crowd to disperse a riot. But they are unlikely to level a city, and they certainly wouldn’t glass the entire planet.

Our best bet would probably actually be nonviolent resistance, as this has a much better track record against benevolent imperialism. Gandhi probably couldn’t have won a war against Britain, but he achieved India’s independence because he was smart enough to fight on the front of public opinion. Likewise, even with one tentacle tied behind their backs by their benevolence, the aliens would still probably be able to win any full-scale direct conflict; but if our nonviolent resistance grew strong enough, they might finally take the hint and realize we don’t want their so-called “help”.

So, how about someone makes that movie? Aliens come to our planet, not to kill us, but to change us, make us “better” according to their standards. QLX coefficients are maximized, and an intrepid few even get their tentacles installed. But the Resistance arises, and splits into two factions: One tries to use violence, and is rapidly crushed by overwhelming firepower, while the other uses nonviolent resistance. Ultimately the Resistance grows strong enough to overthrow the alien provisional government, and they decide to cut their losses and leave our planet. Then, decades later, we go back to normal, and wonder if we made the right decision, or if maybe QLX coefficients really were the most important thing after all.

Believing in civilization without believing in colonialism

JDN 2457541

In a post last week I presented some of the overwhelming evidence that society has been getting better over time, particularly since the start of the Industrial Revolution. I focused mainly on infant mortality rates—babies not dying—but there are lots of other measures you could use as well. Despite popular belief, poverty is rapidly declining, and is now the lowest it’s ever been. War is rapidly declining. Crime is rapidly declining in First World countries, and to the best of our knowledge crime rates are stable worldwide. Public health is rapidly improving. Lifespans are getting longer. And so on, and so on. It’s not quite true to say that every indicator of human progress is on an upward trend, but the vast majority of really important indicators are.

Moreover, there is every reason to believe that this great progress is largely the result of what we call “civilization”, even Western civilization: Stable, centralized governments, strong national defense, representative democracy, free markets, openness to global trade, investment in infrastructure, science and technology, secularism, a culture that values innovation, and freedom of speech and the press. We did not get here by Marxism, nor agragrian socialism, nor primitivism, nor anarcho-capitalism. We did not get here by fascism, nor theocracy, nor monarchy. This progress was built by the center-left welfare state, “social democracy”, “modified capitalism”, the system where free, open markets are coupled with a strong democratic government to protect and steer them.

This fact is basically beyond dispute; the evidence is overwhelming. The serious debate in development economics is over which parts of the Western welfare state are most conducive to raising human well-being, and which parts of the package are more optional. And even then, some things are fairly obvious: Stable government is clearly necessary, while speaking English is clearly optional.

Yet many people are resistant to this conclusion, or even offended by it, and I think I know why: They are confusing the results of civilization with the methods by which it was established.

The results of civilization are indisputably positive: Everything I just named above, especially babies not dying.

But the methods by which civilization was established are not; indeed, some of the greatest atrocities in human history are attributable at least in part to attempts to “spread civilization” to “primitive” or “savage” people.
It is therefore vital to distinguish between the result, civilization, and the processes by which it was effected, such as colonialism and imperialism.

First, it’s important not to overstate the link between civilization and colonialism.

We tend to associate colonialism and imperialism with White people from Western European cultures conquering other people in other cultures; but in fact colonialism and imperialism are basically universal to any human culture that attains sufficient size and centralization. India engaged in colonialism, Persia engaged in imperialism, China engaged in imperialism, the Mongols were of course major imperialists, and don’t forget the Ottoman Empire; and did you realize that Tibet and Mali were at one time imperialists as well? And of course there are a whole bunch of empires you’ve probably never heard of, like the Parthians and the Ghaznavids and the Ummayyads. Even many of the people we’re accustoming to thinking of as innocent victims of colonialism were themselves imperialists—the Aztecs certainly were (they even sold people into slavery and used them for human sacrifice!), as were the Pequot, and the Iroquois may not have outright conquered anyone but were definitely at least “soft imperialists” the way that the US is today, spreading their influence around and using economic and sometimes military pressure to absorb other cultures into their own.

Of course, those were all civilizations, at least in the broadest sense of the word; but before that, it’s not that there wasn’t violence, it just wasn’t organized enough to be worthy of being called “imperialism”. The more general concept of intertribal warfare is a human universal, and some hunter-gatherer tribes actually engage in an essentially constant state of warfare we call “endemic warfare”. People have been grouping together to kill other people they perceived as different for at least as long as there have been people to do so.

This is of course not to excuse what European colonial powers did when they set up bases on other continents and exploited, enslaved, or even murdered the indigenous population. And the absolute numbers of people enslaved or killed are typically larger under European colonialism, mainly because European cultures became so powerful and conquered almost the entire world. Even if European societies were not uniquely predisposed to be violent (and I see no evidence to say that they were—humans are pretty much humans), they were more successful in their violent conquering, and so more people suffered and died. It’s also a first-mover effect: If the Ming Dynasty had supported Zheng He more in his colonial ambitions, I’d probably be writing this post in Mandarin and reflecting on why Asian cultures have engaged in so much colonial oppression.

While there is a deeply condescending paternalism (and often post-hoc rationalization of your own self-interested exploitation) involved in saying that you are conquering other people in order to civilize them, humans are also perfectly capable of committing atrocities for far less noble-sounding motives. There are holy wars such as the Crusades and ethnic genocides like in Rwanda, and the Arab slave trade was purely for profit and didn’t even have the pretense of civilizing people (not that the Atlantic slave trade was ever really about that anyway).

Indeed, I think it’s important to distinguish between colonialists who really did make some effort at civilizing the populations they conquered (like Britain, and also the Mongols actually) and those that clearly were just using that as an excuse to rape and pillage (like Spain and Portugal). This is similar to but not quite the same thing as the distinction between settler colonialism, where you send colonists to live there and build up the country, and exploitation colonialism, where you send military forces to take control of the existing population and exploit them to get their resources. Countries that experienced settler colonialism (such as the US and Australia) have fared a lot better in the long run than countries that experienced exploitation colonialism (such as Haiti and Zimbabwe).

The worst consequences of colonialism weren’t even really anyone’s fault, actually. The reason something like 98% of all Native Americans died as a result of European colonization was not that Europeans killed them—they did kill thousands of course, and I hope it goes without saying that that’s terrible, but it was a small fraction of the total deaths. The reason such a huge number died and whole cultures were depopulated was disease, and the inability of medical technology in any culture at that time to handle such a catastrophic plague. The primary cause was therefore accidental, and not really foreseeable given the state of scientific knowledge at the time. (I therefore think it’s wrong to consider it genocide—maybe democide.) Indeed, what really would have saved these people would be if Europe had advanced even faster into industrial capitalism and modern science, or else waited to colonize until they had; and then they could have distributed vaccines and antibiotics when they arrived. (Of course, there is evidence that a few European colonists used the diseases intentionally as biological weapons, which no amount of vaccine technology would prevent—and that is indeed genocide. But again, this was a small fraction of the total deaths.)

However, even with all those caveats, I hope we can all agree that colonialism and imperialism were morally wrong. No nation has the right to invade and conquer other nations; no one has the right to enslave people; no one has the right to kill people based on their culture or ethnicity.

My point is that it is entirely possible to recognize that and still appreciate that Western civilization has dramatically improved the standard of human life over the last few centuries. It simply doesn’t follow from the fact that British government and culture were more advanced and pluralistic that British soldiers can just go around taking over other people’s countries and planting their own flag (follow the link if you need some comic relief from this dark topic). That was the moral failing of colonialism; not that they thought their society was better—for in many ways it was—but that they thought that gave them the right to terrorize, slaughter, enslave, and conquer people.

Indeed, the “justification” of colonialism is a lot like that bizarre pseudo-utilitarianism I mentioned in my post on torture, where the mere presence of some benefit is taken to justify any possible action toward achieving that benefit. No, that’s not how morality works. You can’t justify unlimited evil by any good—it has to be a greater good, as in actually greater.

So let’s suppose that you do find yourself encountering another culture which is clearly more primitive than yours; their inferior technology results in them living in poverty and having very high rates of disease and death, especially among infants and children. What, if anything, are you justified in doing to intervene to improve their condition?

One idea would be to hold to the Prime Directive: No intervention, no sir, not ever. This is clearly what Gene Roddenberry thought of imperialism, hence why he built it into the Federation’s core principles.

But does that really make sense? Even as Star Trek shows progressed, the writers kept coming up with situations where the Prime Directive really seemed like it should have an exception, and sometimes decided that the honorable crew of Enterprise or Voyager really should intervene in this more primitive society to save them from some terrible fate. And I hope I’m not committing a Fictional Evidence Fallacy when I say that if your fictional universe specifically designed not to let that happen makes that happen, well… maybe it’s something we should be considering.

What if people are dying of a terrible disease that you could easily cure? Should you really deny them access to your medicine to avoid intervening in their society?

What if the primitive culture is ruled by a horrible tyrant that you could easily depose with little or no bloodshed? Should you let him continue to rule with an iron fist?

What if the natives are engaged in slavery, or even their own brand of imperialism against other indigenous cultures? Can you fight imperialism with imperialism?

And then we have to ask, does it really matter whether their babies are being murdered by the tyrant or simply dying from malnutrition and infection? The babies are just as dead, aren’t they? Even if we say that being murdered by a tyrant is worse than dying of malnutrition, it can’t be that much worse, can it? Surely 10 babies dying of malnutrition is at least as bad as 1 baby being murdered?

But then it begins to seem like we have a duty to intervene, and moreover a duty that applies in almost every circumstance! If you are on opposite sides of the technology threshold where infant mortality drops from 30% to 1%, how can you justify not intervening?

I think the best answer here is to keep in mind the very large costs of intervention as well as the potentially large benefits. The answer sounds simple, but is actually perhaps the hardest possible answer to apply in practice: You must do a cost-benefit analysis. Furthermore, you must do it well. We can’t demand perfection, but it must actually be a serious good-faith effort to predict the consequences of different intervention policies.

We know that people tend to resist most outside interventions, especially if you have the intention of toppling their leaders (even if they are indeed tyrannical). Even the simple act of offering people vaccines could be met with resistance, as the native people might think you are poisoning them or somehow trying to control them. But in general, opening contact with with gifts and trade is almost certainly going to trigger less hostility and therefore be more effective than going in guns blazing.

If you do use military force, it must be targeted at the particular leaders who are most harmful, and it must be designed to achieve swift, decisive victory with minimal collateral damage. (Basically I’m talking about just war theory.) If you really have such an advanced civilization, show it by exhibiting total technological dominance and minimizing the number of innocent people you kill. The NATO interventions in Kosovo and Libya mostly got this right. The Vietnam War and Iraq War got it totally wrong.

As you change their society, you should be prepared to bear most of the cost of transition; you are, after all, much richer than they are, and also the ones responsible for effecting the transition. You should not expect to see short-term gains for your own civilization, only long-term gains once their culture has advanced to a level near your own. You can’t bear all the costs of course—transition is just painful, no matter what you do—but at least the fungible economic costs should be borne by you, not by the native population. Examples of doing this wrong include basically all the standard examples of exploitation colonialism: Africa, the Caribbean, South America. Examples of doing this right include West Germany and Japan after WW2, and South Korea after the Korean War—which is to say, the greatest economic successes in the history of the human race. This was us winning development, humanity. Do this again everywhere and we will have not only ended world hunger, but achieved global prosperity.

What happens if we apply these principles to real-world colonialism? It does not fare well. Nor should it, as we’ve already established that most if not all real-world colonialism was morally wrong.

15th and 16th century colonialism fail immediately; they offer no benefit to speak of. Europe’s technological superiority was enough to give them gunpowder but not enough to drop their infant mortality rate. Maybe life was better in 16th century Spain than it was in the Aztec Empire, but honestly not by all that much; and life in the Iroquois Confederacy was in many ways better than life in 15th century England. (Though maybe that justifies some Iroquois imperialism, at least their “soft imperialism”?)

If these principles did justify any real-world imperialism—and I am not convinced that it does—it would only be much later imperialism, like the British Empire in the 19th and 20th century. And even then, it’s not clear that the talk of “civilizing” people and “the White Man’s Burden” was much more than rationalization, an attempt to give a humanitarian justification for what were really acts of self-interested economic exploitation. Even though India and South Africa are probably better off now than they were when the British first took them over, it’s not at all clear that this was really the goal of the British government so much as a side effect, and there are a lot of things the British could have done differently that would obviously have made them better off still—you know, like not implementing the precursors to apartheid, or making India a parliamentary democracy immediately instead of starting with the Raj and only conceding to democracy after decades of protest. What actually happened doesn’t exactly look like Britain cared nothing for actually improving the lives of people in India and South Africa (they did build a lot of schools and railroads, and sought to undermine slavery and the caste system), but it also doesn’t look like that was their only goal; it was more like one goal among several which also included the strategic and economic interests of Britain. It isn’t enough that Britain was a better society or even that they made South Africa and India better societies than they were; if the goal wasn’t really about making people’s lives better where you are intervening, it’s clearly not justified intervention.

And that’s the relatively beneficent imperialism; the really horrific imperialists throughout history made only the barest pretense of spreading civilization and were clearly interested in nothing more than maximizing their own wealth and power. This is probably why we get things like the Prime Directive; we saw how bad it can get, and overreacted a little by saying that intervening in other cultures is always, always wrong, no matter what. It was only a slight overreaction—intervening in other cultures is usually wrong, and almost all historical examples of it were wrong—but it is still an overreaction. There are exceptional cases where intervening in another culture can be not only morally right but obligatory.

Indeed, one underappreciated consequence of colonialism and imperialism is that they have triggered a backlash against real good-faith efforts toward economic development. People in Africa, Asia, and Latin America see economists from the US and the UK (and most of the world’s top economists are in fact educated in the US or the UK) come in and tell them that they need to do this and that to restructure their society for greater prosperity, and they understandably ask: “Why should I trust you this time?” The last two or four or seven batches of people coming from the US and Europe to intervene in their countries exploited them or worse, so why is this time any different?

It is different, of course; UNDP is not the East India Company, not by a longshot. Even for all their faults, the IMF isn’t the East India Company either. Indeed, while these people largely come from the same places as the imperialists, and may be descended from them, they are in fact completely different people, and moral responsibility does not inherit across generations. While the suspicion is understandable, it is ultimately unjustified; whatever happened hundreds of years ago, this time most of us really are trying to help—and it’s working.

The challenges of a global basic income

JDN 2457404

In the previous post I gave you the good news. Now for the bad news.

So we are hoping to implement a basic income of $3,000 per person per year worldwide, eliminating poverty once and for all.

There is no global government to implement this system. There is no global income tax to be collected or refunded. The United Nations and the World Bank, for all the good work that they do, are nowhere near powerful enough (or well-funded enough) to accomplish this feat.

Worse, the people we need to help the most, not coincidentally, live in the countries that are worst-managed. They are surrounded not only by squalor, but also by corruption, war, ethnic tension. Most of the people are underfed, uneducated, and dying from diseases such as malaria and schistomoniasis that we could treat in a day for pocket change. Their infrastructure is either crumbling or nonexistent. Their water is unsafe to drink. And worst of all, many of their governments don’t care. Tyrants like Robert Mugabe, Kim Jong-un, King Salman (of our lovely ally Saudi Arabia), and Isayas Afewerki care nothing for the interests of the people they rule, and are interested only in maximizing their own wealth and power. If we arranged to provide grants to these countries in an amount sufficient to provide the basic income, there’s no reason to think they’d actually provide it; they’d simply deposit the check in their own personal bank accounts, and use it to buy ever more extravagant mansions or build ever greater monuments to themselves. They really do seem to follow a utility function based entirely upon their own consumption; witness your neoclassical rational agent and despair.

There are ways for international institutions and non-governmental organizations to intervene to help people in these countries, and indeed many have done so to considerable effect. As bad as things are, they are much better than they used to be, and they promise to be even better tomorrow. But there is only so much they can do without the force of law at their backs, without the power to tax incomes and print currency.

We will therefore need a new kind of institutional framework, if not a true world government then something very much like it. Establishing this new government will not be easy, and worst of all I see no way to do it other than military force. Tyrants will not give up their power willingly; it will need to be taken from them. We will need to capture and imprison tyrants like Robert Mugabe and Kim Jong Un in the same way that we once did to mob bosses like John Dillinger and Al Capone, for ultimately a tyrant is nothing but a mob boss with an army.Unless we can find some way to target them precisely and smoothly replace their regimes with democracies, this will mean nothing less than war, and it could kill thousands, even millions of people—but millions of people are already dying, and will continue to die as long as we leave these men in power. Sanctions might help (though sanctions kill people too), and perhaps a few can be persuaded to step down, but the rest must be overthrown, by some combination of local revolutions and international military coalitions. The best model I’ve seen for how this might be pulled off is Libya, where Qaddafi was at last removed by an international military force supporting a local revolution—but even Libya is not exactly sunshine and rainbows right now. One of the first things we need to do is seriously plan a strategy for removing repressive dictators with a minimum of collateral damage.

To many, I suspect this sounds like imperialism, colonialism redux. Didn’t so many imperialistic powers say that they were doing it to help the local population? Yes, they did; and one of the facts that we must face up to is that it was occasionally true. Or if helping the local population was not their primary motivation, it was nonetheless a consequence. Countries colonized by the British Empire in particular are now the most prosperous, free nations in the world: The United States, Canada, Australia. South Africa and India might seem like exceptions (GDP PPP per capita of $12,400 and $5,500 respectively) but they really aren’t, compared to what they were before—or even compared to what is next to them today: Angola has a per capita GDP PPP of $7,546 while Bangladesh has only $2,991. Zimbabwe is arguably an exception (per capita GDP PPP of $1,773), but their total economic collapse occurred after the British left. To include Zimbabwe in this basic income program would literally triple the income of most of their population. But to do that, we must first get through Robert Mugabe.

Furthermore, I believe that we can avoid many of the mistakes of the past. We don’t have to do exactly the same thing that countries used to do when they invaded each other and toppled governments. Of course we should not enslave, subjugate, or murder the local population—one would hope that would go without saying, but history shows it doesn’t. We also shouldn’t annex the territory and claim it as our own, nor should we set up puppet governments that are only democratic as long as it serves our interests. (And make no mistake, we have done this, all too recently.) The goal must really be to help the people of countries like Zimbabwe and Eritrea establish their own liberal democracy, including the right to make policies we don’t like—or even policies we think are terrible ideas. If we can do so without war, of course we should. But right now what is usually called “pacifism” leaves millions of people to starve while we do nothing.

The argument that we have previously supported (or even continue to support, ahem, Saudi Arabia) many of these tyrants is sort of beside the point. Yes, that is clearly true; and yes, that is clearly terrible. But do you think that if we simply leave the situation alone they’ll go away? We should never have propped up Saddam Hussein or supported the mujihadeen who became the Taliban; and yes, I do think we could have known that at the time. But once they are there, what do you propose to do now? Wait for them to die? Hope they collapse on their own? Give our #thoughtsandprayers to revolutionaries? When asked what you think we should do, “We shouldn’t have done X” is not a valid response.

Imagine there is a mob boss who had kidnapped several families and is holding them in a warehouse. Suppose that at some point the police supported the mob boss in some way; in a deal to undermine a worse rival mafia family, they looked the other way on some things he did, or even gave him money that he used to strengthen his mob. (With actual police, the former is questionable, but actually done all the time; the latter would be definitely illegal. In the international analogy, both are ubiquitous.) Even suppose that the families who were kidnapped were previously from a part of town that the police would regularly shake down for petty crimes and incessant stop-and-frisks. The police definitely have a lot to answer for in all this; their crimes should not be forgotten. But how does it follow in any way that the police should not intervene to rescue the families from the warehouse? Suppose we even know that the warehouse is heavily guarded, and the resulting firefight may kill some of the hostages we are hoping to save. This gives us reason to negotiate, or to find the swiftest, most precise means to deploy the SWAT teams; but does it give us reason to do nothing?

Once again I think Al Capone is the proper analogy; when the FBI captured Al Capone, they didn’t bomb Chicago to the ground, nor did they attempt to enslave the population of Illinois. They thought of themselves as targeting one man and his lieutenants and re-establishing order and civil government to a free people; that is what we must do in Eritrea and Zimbabwe. (In response to all this, no doubt someone will say: “You just want the US to be the world’s police.” Well, no, I want an international coalition; but yes, given our military and economic hegemony, the US will take a very important role. Above all, yes, I want the world to have police. Why don’t you?)

For everything we did wrong in the recent wars in Afghanistan and Iraq, I think we actually did this part right: Afghanistan’s GDP PPP per capita has risen over 70% since 2002, and Iraq’s is now 17% higher than its pre-war peak. It’s a bit early to say whether we have really established stable liberal democracies there, and the Iraq War surely contributed to the rise of Daesh; but when the previous condition was the Taliban and Saddam Hussein it’s hard not to feel that things are at least somewhat improving. In a generation or two maybe we really will say “Iraq” in the same breath as “Korea” as one of the success stories of prosperous democracies set up after US wars. Or maybe it will all fall apart; it’s hard to say at this point.

So, we must find a way to topple the tyrants. Once that is done, we will need to funnel huge amounts of resources—at least one if not two orders of magnitude larger than our current level of foreign aid into building infrastructure, educating people, and establishing sound institutions. Our current “record high” foreign aid is less than 0.3% of world’s GDP. We have a model for this as well: It’s what we did in West Germany and Japan after WW2, as well as what we did in South Korea after the Korean War. It is not a coincidence that Germany soon regained its status as a world power while Japan and Korea were the first of the “Asian Tigers”, East Asian nations that rose up to join us at a First World standard of living.

Will all of this be expensive? Absolutely. By assuming $3,000 per person per year I am already figuring in an expenditure of $21 trillion per year, indefinitely. This would be the most expensive project upon which humanity has ever embarked. But it could also be the most important—an end to poverty, everywhere, forever. And we have that money, we’re simply using it for other things. At purchasing power parity the world spends over $100 trillion per year. Using 20% of the world’s income to eliminate poverty forever doesn’t seem like such a bad deal to me. (It’s not like it would disappear; it would be immediately spent back into the economy anyway. We might even see growth as a result.)

When dealing with events on this scale, it’s easy to get huge numbers that sound absurd. But even if we assumed that only the US, Europe, and China supported this program, it would only take 37% of our combined income—roughly what we currently spend on housing.

Whenever people complain, “We spend billions of dollars a year on aid, and we haven’t solved world hunger!” the proper answer is, “That’s right; we should be spending trillions.”
