Should we give up on growth?

JDN 2457572

Recently I read this article published by the Post Carbon Institute, “How to Shrink the Economy without Crashing It”, which has been going around environmentalist circles. (I posted on Facebook that I’d answer it in more detail, so here goes.)

This is the far left view on climate change, which is wrong, but not nearly as wrong as even the “mainstream” right-wing view that climate change is not a serious problem and we should continue with business as usual. Most of the Republicans who ran for President this year didn’t believe in using government action to fight climate change, and Donald Trump doesn’t even believe it exists.
This core message of the article is clearly correct:

We know this because Global Footprint Network, which methodically tracks the relevant data, informs us that humanity is now using 1.5 Earths’ worth of resources.

We can temporarily use resources faster than Earth regenerates them only by borrowing from the future productivity of the planet, leaving less for our descendants. But we cannot do this for long.

To be clear, “using 1.5 Earths” is not as bad as it sounds; spending is allow to exceed income at times, as long as you have reason to think that future income will exceed future spending, and this is true not just of money but also of natural resources. You can in fact “borrow from the future”, provided you do actually have a plan to pay it back. And indeed there has been some theoretical work by environmental economists suggesting that we are rightly still in the phase of net ecological dissaving, and won’t enter the phase of net ecological saving until the mid-21st century when our technology has made us two or three times as productive. This optimal path is defined by a “weak sustainability” condition where total real wealth never falls over time, so any natural wealth depleted is replaced by at least as much artificial wealth.

Of course some things can’t be paid back; while forests depleted can be replanted, if you drive species to extinction, only very advanced technology could restore them. And we are driving thousands of species to extinction every single year. Even if we should be optimally dissaving, we are almost certainly depleting natural resources too fast, and depleting natural resources that will be difficult if not impossible to later restore. In that sense, the Post Carbon Institute is right: We must change course toward ecological sustainability.

Unfortunately, their specific ideas of how to do so leave much to be desired. Beyond ecological sustainability, they really argue for two propositions: one is radical but worth discussing, but the other is totally absurd.

The absurd claim is that we should somehow force the world to de-urbanize and regress into living in small farming villages. To show this is a bananaman and not a strawman, I quote:

8. Re-localize. One of the difficulties in the transition to renewable energy is that liquid fuels are hard to substitute. Oil drives nearly all transportation currently, and it is highly unlikely that alternative fuels will enable anything like current levels of mobility (electric airliners and cargo ships are non-starters; massive production of biofuels is a mere fantasy). That means communities will be obtaining fewer provisions from far-off places. Of course trade will continue in some form: even hunter-gatherers trade. Re-localization will merely reverse the recent globalizing trade trend until most necessities are once again produced close by, so that we—like our ancestors only a century ago—are once again acquainted with the people who make our shoes and grow our food.

9. Re-ruralize. Urbanization was the dominant demographic trend of the 20th century, but it cannot be sustained. Indeed, without cheap transport and abundant energy, megacities will become increasingly dysfunctional. Meanwhile, we’ll need lots more farmers. Solution: dedicate more societal resources to towns and villages, make land available to young farmers, and work to revitalize rural culture.

First of all: Are electric cargo ships non-starters? The Ford-class aircraft carrier is electric, specifically nuclear. Nuclear-powered cargo ships would raise a number of issues in terms of practicality, safety, and regulation, but they aren’t fundamentally infeasible. Massive efficient production of biofuels is a fantasy as long as the energy to do it is provided by coal power, but not if it’s provided by nuclear. Perhaps this author’s concept of “infeasible” really just means “infeasible if I can’t get over my irrational fear of nuclear power”. Even electric airliners are not necessarily out of the question; NASA has been experimenting with electric aircraft.

The most charitable reading I can give of this (in my terminology of argument “men”, I’m trying to make a banana out of iron), is as promoting slightly deurbanizing and going back to more like say the 1950s United States, with 64% of people in cities instead of 80% today. Even then this makes less than no sense, as higher urbanization is associated with lower per-capita ecological impact, which frankly shouldn’t even be surprising because cities have such huge economies of scale. Instead of everyone needing a car to get around in the suburbs, we can all share a subway system in the city. If that subway system is powered by a grid of nuclear, solar, and wind power, it could produce essentially zero carbon emissions—which is absolutely impossible for rural or suburban transportation. Urbanization is also associated with slower population growth (or even population decline), and indeed the reason population growth is declining is that rising standard of living and greater urbanization have reduced birth rates and will continue to do so as poor countries reach higher levels of development. Far from being a solution to ecological unsustainability, deurbanization would make it worse.

And that’s not even getting into the fact that you would have to force urban white-collar workers to become farmers, because if we wanted to be farmers we already would be (the converse is not as true), and now you’re actually talking about some kind of massive forced labor-shift policy like the Great Leap Forward. Normally I’m annoyed when people accuse environmentalists of being totalitarian communists, but in this case, I think the accusation might be onto something.

Moving on, the radical but not absurd claim is that we must turn away from economic growth and even turn toward economic shrinkage:

One way or another, the economy (and here we are talking mostly about the economies of industrial nations) must shrink until it subsists on what Earth can provide long-term.

[…]

If nothing is done deliberately to reverse growth or pre-adapt to inevitable economic stagnation and contraction, the likely result will be an episodic, protracted, and chaotic process of collapse continuing for many decades or perhaps centuries, with innumerable human and non-human casualties.

I still don’t think this is right, but I understand where it’s coming from, and like I said it’s worth talking about.

The biggest mistake here lies in assuming that GDP is directly correlated to natural resource depletion, so that the only way to reduce natural resource depletion is to reduce GDP. This is not even remotely true; indeed, countries vary almost as much in their GDP-per-carbon-emission ratio as they do in their per-capita GDP. As usual, #ScandinaviaIsBetter; Norway and Sweden produce about $8,000 in GDP per ton of carbon, while the US produces only about $2,000 per ton. Both poor and rich countries can be found among both the inefficient and the efficient. Saudi Arabia is very rich and produces about $900 per ton, while Liberia is exceedingly poor and produces about $800 per ton. I already mentioned how Norway produces $8,000 per ton, and they are as rich as Saudi Arabia. Yet above them is Mali, which produces almost $11,000 per ton, and is as poor as Liberia. Other notable facts: France is head and shoulders above the UK and Germany at almost $6000 per ton instead of $4300 and $3600 respectively—because France runs almost entirely on nuclear power.

So the real conclusion to draw from this is not that we need to shrink GDP, but that we need to make GDP more like how they do it in Norway or at least how they do it in France, rather than how we do in the US, and definitely not how they do it in Saudi Arabia. Total world emissions are currently about 36 billion tons per year, producing about $108 trillion in GDP, averaging about $3,000 of GDP per ton of carbon emissions. If we could raise the entire world to the ecological efficiency of Norway, we could double world GDP and still be producing less CO2 than we currently are. Turning the entire planet into a bunch of Norways would indeed raise CO2 output, by about a factor of 2; but it would raise standard of living by a factor of 5, and indeed bring about a utopian future with neither war nor hunger. Compare this to the prospect of cutting world GDP in half, but producing it as inefficiently as in Saudi Arabia: This would actually increase global CO2 emissions, almost as much as turning every country into Norway.

But ultimately we will in fact need to slow down or even end economic growth. I ran a little model for you, which shows a reasonable trajectory for global economic growth.

This graph shows the growth rate in productivity slowly declining, along with a much more rapidly declining GDP growth:

Solow_growth

This graph shows the growth trajectory for total real capital and GDP:

Solow_capital

And finally, this is the long-run trend for GDP graphed on a log scale:

Solow_logGDP

The units are arbitrary, though it’s not unreasonable to imagine them as being years and hundreds of dollars in per-capita GDP. If that is indeed what you imagine them to be, my model shows us the Star Trek future: In about 300 years, we rise from a per-capita GDP of $10,000 to one of $165,000—from a world much like today to a world where everyone is a millionaire.

Notice that the growth rate slows down a great deal fairly quickly; by the end of 100 years (i.e., the end of the 21st century), growth has slowed from its peak over 10% to just over 2% per year. By the end of the 300-year period, the growth rate is a crawl of only 0.1%.

Of course this model is very simplistic, but I chose it for a very specific reason: This is not a radical left-wing environmentalist model involving “limits to growth” or “degrowth”. This is the Solow-Swan model, the paradigm example of neoclassical models of economic growth. It is sometimes in fact called simply “the neoclassical growth model”, because it is that influential. I made one very small change from the usual form, which was to assume that the rate of productivity growth would decline exponentially over time. Since productivity growth is exogenous to the model, this is a very simple change to make; it amounts to saying that productivity-enhancing technology is subject to diminishing returns, which fits recent data fairly well but could be totally wrong if something like artificial intelligence or neural enhancement ever takes off.

I chose this because many environmentalists seem to think that economists have this delusional belief that we can maintain a rate of economic growth equal to today indefinitely. David Attenborough famously said “Anyone who believes in indefinite growth in anything physical, on a physically finite planet, is either mad – or an economist.”

Another physicist argued that if we increase energy consumption 2.3% per year for 400 years, we’d literally boil the Earth. Yes, we would, and no economist I know of believes that this is what will happen. Economic growth doesn’t require energy growth, and we do not think growth can or should continue indefinitely—we just think it can and should continue a little while longer. We don’t think that a world standard of living 1000 times as good as Norway is going to happen; we think that a world standard of living equal to Norway is worth fighting for.

Indeed, we are often the ones trying to explain to leaders that they need to adapt to slower growth rates—this is particularly a problem in China, where nationalism and groupthink seems to have convinced many people in China that 7% annual growth is the result of some brilliant unique feature of the great Chinese system, when it is in fact simply the expected high growth rate for an economy that is very poor and still catching up by establishing a capital base. (It’s not so much what they are doing right now, as what they were doing wrong before. Just as you feel a lot better when you stop hitting yourself in the head, countries tend to grow quite fast after they transition out of horrifically terrible economic policy—and it doesn’t get much more terrible than Mao.) Even a lot of the IMF projections are now believed to be too optimistic, because they didn’t account for how China was fudging the numbers and rapidly depleting natural resources.

Some of the specific policies recommended in the article are reasonable, while others go to far.

1. Energy: cap, reduce, and ration it. Energy is what makes the economy go, and expanded energy consumption is what makes it grow. Climate scientists advocate capping and reducing carbon emissions to prevent planetary disaster, and cutting carbon emissions inevitably entails reducing energy from fossil fuels. However, if we aim to shrink the size of the economy, we should restrain not just fossil energy, but all energy consumption. The fairest way to do that would probably be with tradable energy quotas.

I strongly support cap-and-trade on fossil fuels, but I can’t support it on energy in general, unless we get so advanced that we’re seriously concerned about significantly altering the entropy of the universe. Solar power does not have negative externalities, and therefore should not be taxed or capped.

The shift to renewable energy sources is a no-brainer, and I know of no ecologist and few economists who would disagree.

This one is rich, coming from someone who goes on to argue for nonsensical deurbanization:

However, this is a complicated process. It will not be possible merely to unplug coal power plants, plug in solar panels, and continue with business as usual: we have built our immense modern industrial infrastructure of cities, suburbs, highways, airports, and factories to take advantage of the unique qualities and characteristics of fossil fuels.

How will we make our industrial infrastructure run off a solar grid? Urbanization. When everything is in one place, you can use public transportation and plug everything into the grid. We could replace the interstate highway system with a network of maglev lines, provided that almost everyone lived in major cities that were along those lines. We can’t do that if people move out of cities and go back to being farmers.

Here’s another weird one:

Without continued economic growth, the market economy probably can’t function long. This suggests we should run the transformational process in reverse by decommodifying land, labor, and money.

“Decommodifying money”? That’s like skinning leather or dehydrating water. The whole point of money is that it is a maximally fungible commodity. I support the idea of a land tax to provide a basic income, which could go a long way to decommodifying land and labor; but you can’t decommodify money.

The next one starts off sounding ridiculous, but then gets more reasonable:

4. Get rid of debt. Decommodifying money means letting it revert to its function as an inert medium of exchange and store of value, and reducing or eliminating the expectation that money should reproduce more of itself. This ultimately means doing away with interest and the trading or manipulation of currencies. Make investing a community-mediated process of directing capital toward projects that are of unquestioned collective benefit. The first step: cancel existing debt. Then ban derivatives, and tax and tightly regulate the buying and selling of financial instruments of all kinds.

No, we’re not going to get rid of debt. But should we regulate it more? Absolutely. A ban on derivatives is strong, but shouldn’t be out of the question; it’s not clear that even the most useful derivatives (like interest rate swaps and stock options) bring more benefit than they cause harm.

The next proposal, to reform our monetary system so that it is no longer based on debt, is one I broadly agree with, though you need to be clear about how you plan to do that. Positive Money’s plan to make central banks democratically accountable, establish full-reserve banking, and print money without trying to hide it in arcane accounting mechanisms sounds pretty good to me. Going back to the gold standard or something would be a terrible idea. The article links to a couple of “alternative money theorists”, but doesn’t explain further.

Sooner or later, we absolutely will need to restructure our macroeconomic policy so that 4% or even 2% real growth is no longer the expectation in First World countries. We will need to ensure that constant growth isn’t necessary to maintain stability and full employment.

But I believe we can do that, and in any case we do not want to stop global growth just yet—far from it. We are now on the verge of ending world hunger, and if we manage to do it, it will be from economic growth above all else.

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.
