Why did we ever privatize prisons?

JDN 2457103 EDT 10:24.

Since the Reagan administration (it’s always Reagan), the United States has undergone a spree of privatization of public services, in which services that are ordinarily performed by government agencies are instead contracted out to private companies. Enormous damage to our society has been done by this sort of privatization, from healthcare to parking meters.

This process can vary in magnitude.

The weakest form, which is relatively benign, is for the government to buy specific services like food service or equipment manufacturing from companies that already provide them to consumers. There’s no particular reason for the government to make their own toothpaste or wrenches rather than buy them from corporations like Proctor & Gamble and Sears. Toothpaste is toothpaste and wrenches are wrenches.

The moderate form is for the government to contract services to specific companies that may involve government-specific features like security clearances or powerful military weapons. This is already raising a lot of problems: When Northrop-Grumman makes our stealth bombers, and Boeing builds our nuclear ICBMs, these are publicly-traded, for-profit corporations manufacturing some of the deadliest weapons ever created—weapons that could literally destroy human civilization in a matter of minutes. Markets don’t work well in the presence of externalities, and weapons by definition are almost nothing but externalities; their entire function is to cause harm—typically, death—to people without their consent. While this violence may sometimes be justified, it must never be taken lightly; and we are right to be uncomfortable with the military-industrial complex whose shareholders profit from death and destruction. (Eisenhower tried to warn us!) Still, there are some good arguments to be made for this sort of privatization, since many of these corporations already have high-tech factories and skilled engineers that they can easily repurpose, and competitive bids between different corporations can keep the price down. (Of course, with no-bid contracts that no longer applies; and it certainly hasn’t stopped us from spending nearly as much on the military as the rest of the world combined.)

What I’d really like to focus on today is the strongest form of privatization, in which basic government services are contracted out to private companies. This is what happens when you attempt to privatize soldiers, SWAT teams, and prisons—all of which the United States has done since Reagan.

I say “attempt” to privatize because in a very real sense the privatization of these services is incoherent—they are functions so basic to government that simply to do them makes you, de facto, part of the government. (Or, if done without government orders, it would be organized crime.) All you’ve really done by “privatizing” these services is reduced their transparency and accountability, as well as siphoning off a portion of the taxpayer money in the form of profits for shareholders.

The benefits of privatization, when they exist, are due to competition and consumer freedom. The foundation of a capitalist economy is the ability to say “I’ll take my business elsewhere.” (This is why the notion that a bank can sell your loan to someone else is the opposite of a free market; forcing you to write a check to someone you never made a contract with is antithetical to everything the free market stands for.) Actually the closest thing to a successful example of privatized government services is the United States Postal Service, which collects absolutely no tax income. They do borrow from the government and receive subsidies for some of their services—but so does General Motors. Frankly I think the Postal Service has a better claim to privatization than GM, which you may recall only exists today because of a massive government bailout with a net cost to the US government of $11 billion. All the Postal Service does differently is act as a tightly-regulated monopoly that provides high-quality service to everyone at low prices and pays good wages and pensions, all without siphoning profits to shareholders. (They really screwed up my mail forwarding lately, but they are still one of the best postal systems in the world.) It is in many ways the best of both worlds, the efficiency of capitalism with the humanity of socialism.

The Corrections Corporation of America, on the other hand, is the exact opposite, the worst of both worlds, the inefficiency of socialism with the inhumanity of capitalism. It is not simply corrupt but frankly inherently corrupt—there is simply no way you can have a for-profit prison system that isn’t corrupt. Maybe it can be made less corrupt or more corrupt, but the mere fact that shareholders are earning profits from incarcerating prisoners is fundamentally antithetical to a free and just society.

I really can’t stress this enough: Privatizing soldiers and prisons makes no sense at all. It doesn’t even make sense in a world of infinite identical psychopaths; nothing in neoclassical economic theory in any way supports these privatizations. Neoclassical theory is based upon the presumption of a stable government that enforces property rights, a government that provides as much service as necessary exactly at cost and is not attempting to maximize any notion of its own “profit”.

That’s ridiculous, of course—much like the neoclassical rational agent—and more recent work has been done in public choice theory about the various interest groups that act against each other in government, including lobbyists for private corporations—but public choice theory is above all a theory of government failure. It is a theory of why governments don’t work as well as we would like them to—the main question is how we can suppress the influence of special interest groups to advance the public good. Privatization of prisons means creating special interest groups where none existed, making the government less directed at the public good.

Privatizing government services is often described as “reducing the size of government”, usually interpreted in the most narrow sense to mean the tax burden. But Big Government doesn’t mean you pay 22% of GDP instead of 18% of GDP; Big Government means you can be arrested and imprisoned without trial. Even using the Heritage Foundation’s metrics, the correlation between tax burden and overall freedom is positive. Tyrannical societies don’t bother with taxes; they own the oil refineries directly (Venezuela), or print money whenever they want (Zimbabwe), or build the whole society around doing what they want (North Korea).

The incarceration rate is a much better measure of a society’s freedom than the tax rate will ever be—and the US isn’t doing so well in that regard; indeed we have by some measures the highest incarceration rate in the world. Fortunately we do considerably better when it comes to things like free speech and freedom of religion—indeed we are still above average in overall freedom. Though we do imprison more of our people than China, I’m not suggesting that China has a freer society. But why do we imprison so many people?

Well, it seems to have something to do with privatization of prisons. Indeed, there is a strong correlation between the privatization of US prisons and the enormous explosion of incarceration in the United States. In fact privatized prisons don’t even reduce the tax burden, because privatization does not decrease demand and “privatized” prisons must still be funded by taxes. Prisons do not have customers who choose between different competing companies and shop for the highest quality and lowest price—prisoners go to the prison they are assigned to and they can’t leave (which is really the whole point). Even competition at the purchase end doesn’t make much sense, since the government can’t easily transfer all the prisoners to a new company. Maybe they could transfer ownership of the prison to a different company, but even then the transition costs would be substantial, and besides, there are only a handful of prison corporations that corner most of the (so-called) market.

There is simply no economic basis for privatization of prisons. Nothing in either neoclassical theory or more modern cognitive science in any way supports the idea. So the real question is: Why did we ever privatize prisons?

Basically there is only one reason: Ideology. The post-Reagan privatization spree was not actually based on economics—it was based on economic ideology. Either because they actually believed it, or by the Upton Sinclair Principle, a large number of economists adopted a radical far-right ideology that government basically should not exist—that the more we give more power to corporations and less power to elected officials the better off we will be.

They defended this ideology on vaguely neoclassical grounds, mumbling something about markets being more efficient; but this isn’t even like cutting off the wings of the airplane because we’re assuming frictionless vacuum—it’s like cutting off the engines of the airplane because we simply hate engines and are looking for any excuse to get rid of them. There is absolutely nothing in neoclassical economic theory that says it would be efficient or really beneficial in any way to privatize prisons. It was all about taking power away from the elected government and handing it over to for-profit corporations.

This is a bit of consciousness-raising I’m trying to do: Any time you hear someone say that something should be apolitical, I want you to substitute the word undemocratic. When they say that judges shouldn’t be elected so that they can be apolitical—they mean undemocratic. When they say that the Federal Reserve should be independent of politics—they mean independent of voting. They want to take decision power away from the public at large and concentrate it more in the hands of an elite. People who say this sort of thing literally do not believe in democracy.

To be fair, there may actually be good reasons to not believe in democracy, or at least to believe that democracy should be constrained by a constitution and a system of representation. Certain rights are inalienable, regardless of what the voting public may say, which is why we need a constitution that protects those rights above all else. (In theory… there’s always the PATRIOT ACT, speaking of imprisoning people without trial.) Moreover, most people are simply not interested enough—or informed enough—to vote on every single important decision the government makes. It makes sense for us to place this daily decision-making power in the hands of an elite—but it must be an elite we choose.

And yes, people often vote irrationally. One of the central problems in the United States today is that almost half the population consistently votes against rational government and their own self-interest on the basis of a misguided obsession with banning abortion, combined with a totally nonsensical folk theory of economics in which poor people are poor because they are lazy, the government inherently destroys whatever wealth it touches, and private-sector “job creators” simply hand out jobs to other people because they have extra money lying around. Then of course there’s—let’s face it—deep-seated bigotry toward women, racial minorities, and LGBT people. (The extreme hatred toward Obama and suspicion that he isn’t really born in the US really can’t be explained any other way.) In such circumstances it may be tempting to say that we should give up on democracy and let expert technocrats take charge; but in the absence of democratic safeguards, technocracy is little more than another name for oligarchy. Maybe it’s enough that the President appoints the Federal Reserve chair and the Supreme Court? I’m not so sure. Ben Bernanke definitely handled the Second Depression better than Congress did, I’ll admit; but I’m not sure Alan Greenspan would have in his place, and given his babbling lately about returning to Bretton Woods I’m pretty sure Paul Volcker wouldn’t have. (If you don’t see what’s wrong with going back to Bretton Woods, which was basically a variant of the gold standard, you should read what Krugman has to say about the gold standard.) So basically we got lucky and our monetary quasi-tyrant was relatively benevolent and wise. (Or maybe Bernanke was better because Obama appointed him, while Reagan appointed Greenspan. Carter appointed Volcker, oddly enough; but Reagan reappointed him. It’s always Reagan.) And if you could indeed ensure that tyrants would always be benevolent and wise, tyranny would be a great system—but you can’t.

Democracy doesn’t always lead to the best outcomes, but that’s really not what it’s for. Rather, democracy is for preventing the worst outcomes—no large-scale famine has ever occurred under a mature democracy, nor has any full-scale genocide. Democracies do sometimes forcibly “relocate” populations (particularly indigenous populations, as the US did under Andrew Jackson), and we should not sugar-coat that; people are forced out of their homes and many die. It could even be considered something close to genocide. But no direct and explicit mass murder of millions has ever occurred under a democratic government—no, the Nazis were not democratically elected—and that by itself is a fully sufficient argument for democracy. It could be true that democracies are economically inefficient (they are economically efficient), unbearably corrupt (they are less corrupt), and full of ignorant idiotic hicks (they have higher average educational attainment), and democracy would still be better simply because it prevents famine and genocide. As Churchill said, “Democracy is the worst system, except for all the others.”

Indeed, I think the central reason why American democracy isn’t working well right now is that it’s not very democratic; a two-party system with a plurality “first-past-the-post” vote is literally the worst possible voting system that can still technically be considered democracy. Any worse than that and you only have one party. If we had a range voting system (which is mathematically optimal) and say a dozen parties (they have about a dozen parties in France), people would be able to express their opinions more clearly and in more detail, with less incentive for strategic voting. We probably wouldn’t have such awful turnout at that point, and after realizing that they actually had such a strong voice, maybe people would even start educating themselves about politics in order to make better decisions.

Privatizing prisons and soldiers takes us in exactly the opposite direction: It makes our government deeply less democratic, fundamentally less accountable to voters. It hands off the power of life and death to institutions whose sole purpose for existence is their own monetary gain. We should never have done it—and we must undo it as soon as we possibly can.

Beware the false balance

JDN 2457046 PST 13:47.

I am now back in Long Beach, hence the return to Pacific Time. Today’s post is a little less economic than most, though it’s certainly still within the purview of social science and public policy. It concerns a question that many academic researchers and in general reasonable, thoughtful people have to deal with: How do we remain unbiased and nonpartisan?

This would not be so difficult if the world were as the most devoted “centrists” would have you believe, and it were actually the case that both sides have their good points and bad points, and both sides have their scandals, and both sides make mistakes or even lie, so you should never take the side of the Democrats or the Republicans but always present both views equally.

Sadly, this is not at all the world in which we live. While Democrats are far from perfect—they are human beings after all, not to mention politicians—Republicans have become completely detached from reality. As Stephen Colbert has said, “Reality has a liberal bias.” You know it’s bad when our detractors call us the reality-based community. Treating both sides as equal isn’t being unbiased—it’s committing a balance fallacy.

Don’t believe me? Here is a list of objective, scientific facts that the Republican Party (and particularly its craziest subset, the Tea Party) has officially taken political stances against:

  1. Global warming is a real problem, and largely caused by human activity. (The Republican majority in the Senate voted down a resolution acknowledging this.)
  2. Human beings share a common ancestor with chimpanzees. (48% of Republicans think that we were created in our present form.)
  3. Animals evolve over time due to natural selection. (Only 43% of Republicans believe this.)
  4. The Earth is approximately 4.5 billion years old. (Marco Rubio said he thinks maybe the Earth was made in seven days a few thousand years ago.)
  5. Hydraulic fracturing can trigger earthquakes.(Republican in Congress are trying to nullify local regulations on fracking because they insist it is so safe we don’t even need to keep track.)
  6. Income inequality in the United States is the worst it has been in decades and continues to rise. (Mitt Romney said that the concern about income inequality is just “envy”.)
  7. Progressive taxation reduces inequality without adversely affecting economic growth. (Here’s a Republican former New York Senator saying that the President “should be ashamed” for raising taxes on—you guessed it—”job creators”.)
  8. Moderate increases in the minimum wage do not yield significant losses in employment. (Republicans consistently vote against even small increases in the minimum wage, and Democrats consistently vote in favor.)
  9. The United States government has no reason to ever default on its debt. (John Boehner, now Speaker of the House, once said that “America is broke” and if we don’t stop spending we’ll never be able to pay the national debt.)
  10. Human embryos are not in any way sentient, and fetuses are not sentient until at least 17 weeks of gestation, probably more like 30 weeks. (Yet if I am to read it in a way that would make moral sense, “Life begins at conception”—which several Republicans explicitly endorsed at the National Right to Life Convention—would have to imply that even zygotes are sentient beings. If you really just meant “alive”, then that would equally well apply to plants or even bacteria. Sentience is the morally relevant category.)

And that’s not even counting the Republican Party’s association with Christianity and all of the objectively wrong scientific claims that necessarily entails—like the existence of an afterlife and the intervention of supernatural forces. Most Democrats also self-identify as Christian, though rarely with quite the same fervor (the last major Democrat I can think of who was a devout Christian was Jimmy Carter), probably because most Americans self-identify as Christian and are hesitant to elect an atheist President (despite the fact that 93% of the National Academy of Sciences is comprised of atheists and the higher your IQ the more likely you are to be an atheist; we wouldn’t want to elect someone who agrees with smart people, now would we?).

It’s true, there are some other crazy ideas out there with a left-wing slant, like the anti-vaccination movement that has wrought epidemic measles upon us, the anti-GMO crowd that rejects basic scientific facts about genetics, and the 9/11 “truth” movement that refuses to believe that Al Qaeda actually caused the attacks. There are in fact far-left Marxists out there who want to tear down the whole capitalist system by glorious revolution and replace it with… er… something (they’re never quite clear on that last point). But none of these things are the official positions of standing members of Congress.

The craziest belief by a standing Democrat I can think of is Dennis Kucinich’s belief that he saw an alien spacecraft. And to be perfectly honest, alien spacecraft are about a thousand times more plausible than Christianity in general, let alone Creationism. There almost certainly are alien spacecraft somewhere in the universe—just most likely so far away we’ll need FTL to encounter them. Moreover, this is not Kucinich’s official position as a member of Congress and it’s not something he has ever made policy based upon.

Indeed, if you’re willing to include the craziest individuals with no real political power who identify with a particular side of the political spectrum, then we should include on the right-wing side people like the Bundy militia in Nevada, neo-Nazis in Detroit, and the dozens of KKK chapters across the US. Not to mention this pastor who wants to murder all gay people in the world (because he truly believes what Leviticus 20:13 actually and clearly says).

If you get to include Marxists on the left, then we get to include Nazis on the right. Or, we could be reasonable and say that only the official positions of elected officials or mainstream pundits actually count, in which case Democrats have views that are basically accurate and reasonable while the majority of Republicans have views that are still completely objectively wrong.

There’s no balance here. For every Democrat who is wrong, there is a Republicans who is totally delusional. For every Democrat who distorts the truth, there is a Republican who blatantly lies about basic facts. Not to mention that for every Democrat who has had an ill-advised illicit affair there is a Republican who has committed war crimes.

Actually war crimes are something a fair number of Democrats have done as well, but the difference still stands out in high relief: Barack Obama has ordered double-tap drone strikes that are in violation of the Geneva Convention, but George W. Bush orchestrated a worldwide mass torture campaign and launched pointless wars that slaughtered hundreds of thousands of people. Bill Clinton ordered some questionable CIA operations, but George H.W. Bush was the director of the CIA.

I wish we had two parties that were equally reasonable. I wish there were two—or three, or four—proposals on the table in each discussion, all of which had merits and flaws worth considering. Maybe if we somehow manage to get the Green Party a significant seat in power, or the Social Democrat party, we can actually achieve that goal. But that is not where we are right now. Right now, we have the Democrats, who have some good ideas and some bad ideas; and then we have the Republicans, who are completely out of their minds.

There is an important concept in political science called the Overton window; it is the range of political ideas that are considered “reasonable” or “mainstream” within a society. Things near the middle of the Overton window are considered sensible, even “nonpartisan” ideas, while things near the edges are “partisan” or “political”, and things near but outside the window are seen as “extreme” and “radical”. Things far outside the window are seen as “absurd” or even “unthinkable”.

Right now, our Overton window is in the wrong place. Things like Paul Ryan’s plan to privatize Social Security and Medicare are seen as reasonable when they should be considered extreme. Progressive income taxes of the kind we had in the 1960s are seen as extreme when they should be considered reasonable. Cutting WIC and SNAP with nothing to replace them and letting people literally starve to death are considered at most partisan, when they should be outright unthinkable. Opposition to basic scientific facts like climate change and evolution is considered a mainstream political position—when in terms of empirical evidence Creationism should be more intellectually embarrassing than being a 9/11 truther or thinking you saw an alien spacecraft. And perhaps worst of all, military tactics like double-tap strikes that are literally war crimes are considered “liberal”, while the “conservative” position involves torture, worldwide surveillance and carpet bombing—if not outright full-scale nuclear devastation.

I want to restore reasonable conversation to our political system, I really do. But that really isn’t possible when half the politicians are totally delusional. We have but one choice: We must vote them out.

I say this particularly to people who say “Why bother? Both parties are the same.” No, they are not the same. They are deeply, deeply different, for all the reasons I just outlined above. And if you can’t bring yourself to vote for a Democrat, at least vote for someone! A Green, or a Social Democrat, or even a Libertarian or a Socialist if you must. It is only by the apathy of reasonable people that this insanity can propagate in the first place.

Fear not the deficit

JDN 2456984 PST 12:20.

The deficit! It’s big and scary! And our national debt is rising by the second, says a “debt clock” that is literally just linearly extrapolating the trend. You don’t actually think that there are economists marking down every single dollar the government spends and uploading it immediately, do you? We’ve got better things to do. Conservatives will froth at the mouth over how Obama is the “biggest government spender in world history“, which is true if you just look at the dollar amounts, but of course it is; Obama is the president of the richest country in world history. If the government continues to tax at the same rate and spend what it taxes, government spending will be a constant proportion of GDP (which isn’t quite true, but it’s pretty close; there are ups and downs but for the last 40 years or so federal spending is generally in the range 30% to 35% of GDP), and the GDP of the United States is huge, and far beyond that of any other nation not only today, but ever. This is particularly true if you use nominal dollars, but it’s even true if you use inflation-adjusted real GDP. No other nation even gets close to US GDP, which is about to reach $17 trillion a year (unless you count the whole European Union as a nation, in which case it’s a dead heat).

China recently passed us if you use purchasing-power-parity, but that really doesn’t mean much, because purchasing-power-parity, or PPP, is a measure of standard of living, not a measure of a nation’s total economic power. If you want to know how well people in a country live, you use GDP per capita (that is, per person) PPP. But if you want to know a country’s capacity to influence the world economy, what matters is so-called real GDP, which is adjusted for inflation and international exchange rates. The difference is that PPP will tell you how many apples a person can buy, but real GDP will tell you how many aircraft carriers a government can build. The US is still doing quite well in that department, thank you; we have 10 of the world’s 20 active aircraft carriers, which is to say as many as everyone else combined. The US has 4% of the world’s population and 24% of the world’s economic output.

In particular, GDP in the US has been growing rather steadily since the Great Recession, and we are now almost recovered from the Second Depression and back to our equilibrium level of unemployment and economic growth. As the economy grows, government spending grows alongside it. Obama has actually presided over a decrease in the proportion of government spending relative to GDP, largely because of all this political pressure to reduce the deficit and stop the growth of the national debt. Under Obama the deficit has dropped dramatically.

But what is the deficit, anyway? And how can the deficit be decreasing if the debt clock keeps ticking up?

The government deficit is simply the difference between total government spending and total government revenue. If the government spends $3.90 trillion and takes in $3.30 trillion, the deficit is going to be $0.60 trillion, or $600 billion. In the rare case that you take in more than you spend, the deficit would be negative; we call that a surplus instead. (This almost never happens.)

Because of the way the US government is financed, the deficit corresponds directly to the national debt, which is the sum of all outstanding loans to the government. Every time the government spends more than it takes in, it makes up the difference by taking out a loan, in the form of a Treasury bond. As long as the deficit is larger than zero, the debt will increase. Think of the debt as where you are, and the deficit as how fast you’re going; you can be slowing down, but you’ll continue to move forward as long as you have some forward momentum.

Who is giving us these loans? You can look at the distribution of bondholders here. About a third of the debt is owned by the federal government itself, which makes it a very bizarre notion of “debt” indeed. Of the rest, 21% is owned by states or the Federal Reserve, so that’s also a pretty weird kind of debt. Only 55% of the total debt is owned by the public, and of those 39% are people and corporations within the United States. That means that only 33% of the national debt is actually owned by foreign people, corporations, or governments. What we actually owe to China is about $1.4 trillion. That’s a lot of money (it’s literally enough to make an endowment that would end world hunger forever), but our total debt is almost $18 trillion, so that’s only 8%.

When most people see these huge figures they panic: “Oh my god, we owe $18 trillion! How will we ever repay that!” Well, first of all, our GDP is $17 trillion, so we only owe a little over one year of income. (I wish I only owed one year of income in student loans….)

But in fact we don’t really owe it at all, and we don’t need to ever repay it. Chop off everything that’s owned by US government institutions (including the Federal Reserve, which is only “quasi-governmental”), and the figure drops down to $9.9 trillion. If by we you mean American individuals and corporations, then obviously we don’t owe back the debt that’s owned by ourselves, so take that off; now you’re looking at $6 trillion. That’s only about 4 months of total US economic output, or less than two years of government revenue.

And it gets better! The government doesn’t need to somehow come up with that money; they don’t even have to raise it in taxes. They can print that money, because the US government has a sovereign currency and the authority to print as much as we want. Really, we have the sovereign currency, because the US dollar is the international reserve currency, the currency that other nations hold in order to make exchanges in foreign markets. Other countries buy our money because it’s a better store of value than their own. Much better, in fact; the US has the most stable inflation rate in the world, and has literally never undergone hyperinflation. Better yet, the last time we had prolonged deflation was the Great Depression. This system is self-perpetuating, because being the international reserve currency also stabilizes the value of your money.

This is why it’s so aggravating to me when people say things like “the government can’t afford that” or “the government is broke” or “that money needs to come from somewhere”. No, the government can’t be broke! No, the money doesn’t have to come from somewhere! The US government is the somewhere from which the world’s money comes. If there is one institution in the world that can never, ever be broke, it is the US government. This gives our government an incredible amount of power—combine that with our aforementioned enormous GDP and fleet of aircraft carriers, and you begin to see why the US is considered a global hegemon.

To be clear: I’m not suggesting we eliminate all taxes and just start printing money to pay for everything. Taxes are useful, and we should continue to have them—ideally we would make them more progressive than they presently are. But it’s important to understand why taxes are useful; it’s really not that they are “paying for” government services. It’s actually more that they are controlling the money supply. The government creates money by spending, then removes money by taxing; in this way we maintain a stable growth of the money supply that allows us to keep the economy running smoothly and maintain inflation at a comfortable level. Taxes also allow the government to redistribute income from those who have it and save it to those who need it and will spend it—which is all the more reason for them to be progressive. But in theory we could eliminate all taxes without eliminating government services; it’s just that this would cause a surge in inflation. It’s a bad idea, but by no means impossible.

When we have a deficit, the national debt increases. This is not a bad thing. This is a fundamental misconception that I hope to disabuse you of: Government debt is not like household debt or corporate debt. When people say things like “we need to stop spending outside our means” or “we shouldn’t put wars on the credit card”, they are displaying a fundamental misunderstanding of what government debt is. The government simply does not operate under the same kind of credit constraints as you and I.

First, the government controls its own interest rates, and they are always very low—typically the lowest in the entire economy. That already gives it a lot more power over its debt than you or I have over our own.

Second, the government has no reason to default, because they can always print more money. That’s probably why bondholders tolerate the fact that the government sets its own interest rates; sure, it only pays 0.5%, but it definitely pays that 0.5%.

Third, government debt plays a role in the functioning of global markets; one of the reasons why China is buying up so much of our debt is so that they can keep the dollar high in value and thus maintain their trade surplus. (This is why whenever someone says something like, “The government needs to stop going further into debt, just like how I tightened my belt and paid off my mortgage!” I generally reply, “So when was the last time someone bought your debt in order to prop up your currency?”) This is also why we can’t get rid of our trade deficit and maintain a “strong dollar” at the same time; anyone who wants to do that may feel patriotic, but they are literally talking nonsense. The stronger the dollar, the higher the trade deficit.

Fourth, as I already hinted at above, the government doesn’t actually need debt at all. Government debt, like taxation, is not actually a source of funding; it is a tool of monetary policy. (If you’re going to quote one sentence from this post, it should be the previous; that basically sums up what I’m saying.) Even without raising taxes or cutting spending, the government could choose not to issue bonds, and instead print cash. You could make a sophisticated economic argument for how this is really somehow “issuing debt with indefinite maturity at 0% interest”; okay, fine. But it’s not what most people think of when they think of debt. (In fact, sophisticated economic arguments can go quite the opposite way: there’s a professor at Harvard I may end up working with—if I get into Harvard for my PhD of course—who argues that the federal debt and deficit are literally meaningless because they can be set arbitrarily by policy. I think he goes too far, but I see his point.) This is why many economists were suggesting that in order to get around ridiculous debt-ceiling intransigence Obama could simply Mint the Coin.

Government bonds aren’t really for the benefit of the government, they’re for the benefit of society. They allow the government to ensure that there is always a perfectly safe investment that people can buy into which will anchor interest rates for the rest of the economy. If we ever did actually pay off all the Treasury bonds, the consequences could be disastrous.

Fifth, the government does not have a credit limit; they can always issue more debt (unless Congress is filled with idiots who won’t raise the debt ceiling!). The US government is the closest example in the world to what neoclassical economists call a perfect credit market. A perfect credit market is like an ideal rational agent; these sort of things only exist in an imaginary world of infinite identical psychopaths. A perfect credit market would have perfect information, zero transaction cost, zero default risk, and an unlimited quantity of debt; with no effort at all you could take out as much debt as you want and everyone would know that you are always guaranteed to pay it back. This is in most cases an utterly absurd notion—but in the case of the US government it’s actually pretty close.

Okay, now that I’ve deluged you with reasons why the national debt is fundamentally different from a household mortgage or corporate bond, let’s get back to talking about the deficit. As I mentioned earlier, the deficit is almost always positive; the government is almost always spending more money than it takes in. Most people think that is a bad thing; it is not.

It would be bad for a corporation to always run a deficit, because then it would never make a profit. But the government is not a for-profit corporation. It would be bad for an individual to always run a deficit, because eventually they would go bankrupt. But the government is not an individual.

In fact, the government running a deficit is necessary for both corporations to make profits and individuals to gain net wealth! The government is the reason why our monetary system is nonzero-sum.

This is actually so easy to see that most people who learn about it react with shock, assuming that it can’t be right. There can’t be some simple and uncontroversial equation that shows that government deficits are necessary for profits and savings. Actually, there is; and the fact that we don’t talk about this more should tell you something about the level of sophistication in our economic discourse.

Individuals do work, get paid wages W. (This also includes salaries and bonuses; it’s all forms of labor income.) They also get paid by government spending, G, and pay taxes, T. Let’s pretend that all taxing and spending goes to people and not corporations. This is pretty close to true, especially since corporations as big as Boeing frequently pay nothing in taxes. Corporate subsidies, while ridiculous, are also a small portion of spending—no credible estimate is above $300 billion a year, or less than 10% of the budget. (Without that assumption the equation has a couple more terms, but the basic argument doesn’t change.) People use their money to buy consumption goods, C. What they don’t spend they save, S.

S = (W + G – T) – C

I’m going to rearrange this for reasons that will soon become clear:

S = (W – C) + (G – T)

I’ll also subtract investment I from both sides, again for reasons that will become clear:

S – I = (W – C – I) + (G – T)

Corporations hire workers and pay them W. They make consumption goods which are then sold for C. They also sell to foreign companies and buy from foreign companies, exporting X and importing M. Since we have a trade deficit, this means that X < M. Finally, they receive investment I that comes in the form of banks creating money through loans (yes, banks can create money). Most of our monetary policy is in the form of trying to get banks to create more money by changing interest rates. Only when desperate do we actually create the money directly (I’m not sure why we do it this way). In any case, this yields a total net profit P.

P = C + I – W + (X – M)

Now, if the economy is functioning well, we want profits and savings to both be positive—both people and corporations will have more money on average next year then they had this year. This means that S > 0 and P > 0. We also don’t want the banks loaning out more money than people save—otherwise people go ever further into debt—so we actually want S > I, or S – I > 0. If S – I > 0, people are paying down their debts and gaining net wealth. If S – I < 0, people are going further into debt and losing net wealth. In a well-functioning economy we want people to be gaining net wealth.

In order to have P > 0, because X – M < 0 we need to have C + I > W. People have to spend more on consumption and investment than they are paid in wages—have to, absolutely have to, as a mathematical law—in order for corporations to make a profit.

But then if C + I > W, W – C – I < 0, which means that the first term of the savings equation is negative. In order for savings to be positive, it must be—again as a mathematical law—that G – T > 0, which means that government spending exceeds taxes. In order for both corporations to profit and individuals to save at the same time, the government must run a deficit.

There is one other way, actually, and that’s for X – M to be positive, meaning you run a trade surplus. But right now we don’t, and moreover, the world as a whole necessarily cannot. For the world as a whole, X = M. This will remain true at least until we colonize other planets. This means that in order for both corporate profits and individual savings to be positive worldwide, overall governments worldwide must spend more than they take in. It has to be that way, otherwise the equations simply don’t balance.

You can also look at it another way by adding the equations for S – I and P:

S – I + P = (G – T) + (X – M)

Finally, you can also derive this a third way. This is your total GDP which we usually call Y (“yield”, I think?); it’s equal to consumption plus investment plus government spending, plus net exports:

Y = C + I + G + (X – M)

It’s also equal to consumption plus profit plus saving plus taxes:

Y = C + P + S + T

So those two things must be the same:

C + S + T + P = C + I + G + (X – M)

Canceling and rearranging we get:

(S – I) + P = (G – T) + (X – M)

The sum of saving minus investment (which we can sort of think of as “net saving”) plus profit is equal to the sum of the government deficit and the trade surplus. (Usually you don’t see P in this sectoral balances equation because no distinction is made between consumers and corporations and P is absorbed into S.)

From the profit equation:

W = C + I + (X – M) – P

Put that back into our GDP equation:

Y = W + P + G

GDP is wages plus profits plus government spending.

That’s a lot of equations; simple equations, but yes, equations. Lots of people are scared by equations. So here, let me try to boil it down to a verbal argument. When people save and corporations make profits, money gets taken out of circulation. If no new money is added, the money supply will decrease as a result; this shrinks the economy (mathematically it must absolutely shrink it in nominal terms; theoretically it could cause deflation and not reduce real output, but in practice real output always goes down because deflation causes its own set of problems). New money can be created by banks, but the mechanism of creation requires that people go further into debt. This is unstable, and eventually people can’t borrow anymore and the whole financial system comes crashing down. The better way, then, is for the government to create new money. Yes, as we currently do things, this means the government will go further into debt; but that’s all right, because the government can continue to increase its debt indefinitely without having to worry about hitting a ceiling and making everything fall apart. We could also just print money instead, and in fact I think in many cases this is what we should do—but for whatever reason people always freak out when you suggest such a thing, invariably mentioning Zimbabwe. (And yes, Zimbabwe is in awful shape; but they didn’t just print money to cover a reasonable amount of deficit spending. They printed money to line their own pockets, and it was thousands of times more than what I’m suggesting. Also Zimbabwe has a much smaller economy; $1 trillion is 5% of US GDP, but it’s 8,000% of Zimbabwe’s. I’m suggesting we print maybe 4% of GDP; at the peak of the hyperinflation they printed something more like 100,000%.)

One last thing before I go. If investment suddenly drops, net saving will go up. If the government deficit and trade deficit remain constant, profits must go down. This drives firms into bankruptcy, driving wages down as well. This makes GDP fall—and you get a recession. A similar effect would occur if consumption suddenly drops. In both cases people will be trying to increase their net wealth, but in fact they won’t be able to—this is what’s called the paradox of thrift. You actually want to increase the government deficit under these circumstances, because then you will both add to GDP directly and allow profits and wages to go back up and raise GDP even further. Because GDP has gone down, tax income will go down, so if you insist on balancing the budget, you’ll cut spending and only make things worse.

Raising the government deficit generally increases economic growth. From these simple equations it looks like you could raise GDP indefinitely, but these are nominal figures—actual dollar amounts—so after a certain point all you’d be doing is creating inflation. Where exactly that point is depends on how your economy is performing relative to its potential capacity. In a recession you are far below capacity, so that’s just the time to spend. You’d only want a budget surplus if you actually thought you were above long-run capacity, because you’re depleting natural resources or causing too much inflation or something like that. And indeed, we hardly ever see budget surpluses.

So that, my dear reader, is why we don’t need to fear the deficit. Government debt is nothing like other forms of debt; profits and savings depend upon the government spending more than it takes in; deficits are highly beneficial during recessions; and the US government is actually in a unique position to never worry about defaulting on its debt.
