Crunch

Оглавление

And yet, good as life is, today life is not good. Happy statistics of recent improvement sound as hollow to a laid-off car worker in Detroit or an evicted house owner in Reykjavik as they would to a cholera victim in Zimbabwe or a genocide refugee in Congo. War, disease, corruption and hate still disfigure the lives of millions; nuclear terrorism, rising sea levels and pandemic flu may yet make the twenty-first century a dreadful place. True, but assuming the worst will not avert these fates; striving to continue improving the human lot may. It is precisely because so much human betterment has been shown to be possible in recent centuries that the continuing imperfection of the world places a moral duty on humanity to allow economic evolution to continue. To prevent change, innovation and growth is to stand in the way of potential compassion. Let it never be forgotten that, by propagating excessive caution about genetically modified food aid, some pressure groups may have exacerbated real hunger in Zambia in the early 2000s. The precautionary principle – better safe than sorry – condemns itself: in a sorry world there is no safety to be found in standing still.

More immediately, the financial crash of 2008 has caused a deep and painful recession that will generate mass unemployment and real hardship in many parts of the world. The reality of rising living standards feels to many today to be a trick, a pyramid scheme achieved by borrowing from the future.

Until he was rumbled in 2008, Bernard Madoff offered his investors high and steady returns of more than 1 per cent a month on their money for thirty years. He did so by paying new investors’ capital out to old investors as revenue, a chain-letter con trick that could not last. When the music stopped, $65 billion of investors’ funds had been looted. It was roughly what John Law did in Paris with the Mississippi Company in 1719, what John Blunt did in London with the South Sea company in 1720, what Charles Ponzi did in Boston in 1920 with reply coupons for postage stamps, what Ken Lay did with Enron’s stock in 2001.

Is it possible that not just the recent credit boom, but the entire postwar rise in living standards was a Ponzi scheme, made possible by the gradual expansion of credit? That we have in effect grown rich by borrowing the means from our children and that a day of reckoning is now at hand? It is certainly true that your mortgage is borrowed (via a saver somewhere else, perhaps in China) from your future self, who will pay it off. It is also true on both sides of the Atlantic that your state pension will be funded by your children’s taxes, not by your payroll contributions as so many think.

But there is nothing unnatural about this. In fact, it is a very typical human pattern. By the age of 15 chimpanzees have produced about 40 per cent and consumed about 40 per cent of the calories they will need during their entire lives. By the same age, human hunter-gatherers have consumed about 20 per cent of their lifetime calories, but produced just 4 per cent. More than any other animal, human beings borrow against their future capabilities by depending on others in their early years. A big reason for this is that hunter-gatherers have always specialised in foods that need extraction and processing – roots that need to be dug and cooked, clams that need to be opened, nuts that need to be cracked, carcasses that need to be butchered – whereas chimpanzees eat things that simply need to be found and gathered, like fruit or termites. Learning to do this extraction and processing takes time, practice and a big brain, but once a human being has learnt, he or she can produce a huge surplus of calories to share with the children. Intriguingly, this pattern of production over the lifespan in hunter-gatherers is more like the modern Western lifestyle than it is like the farming, feudal or early industrial lifestyles. That is to say, the notion of children taking twenty years even to start to bring in more than they consume, and then having forty years of very high productivity, is common to hunter-gatherers and modern societies, but was less true in the period in between, when children could and did go to work to support their own consumption.

The difference today is that intergenerational transfers take a more collective form – income tax on all productive people in their prime pays for education for all, for example. In that sense, the economy (like a chain letter, but unlike a shark, actually) must keep moving forward or it collapses. The banking system makes it possible for people to borrow and consume when they are young and to save and lend when they are old, smoothing their family living standards over the decades. Posterity can pay for its ancestors’ lives because posterity can be richer through innovation. If somebody somewhere takes out a mortgage, which he will repay in three decades’ time, to invest in a business that invents a gadget that saves his customers time, then that money, brought forward from the future, will enrich both him and those customers to the point where the loan can be repaid to posterity. That is growth. If, on the other hand, somebody takes out a loan just to support his luxury lifestyle, or to speculate on asset markets by buying a second home, then posterity will be the loser. That is what, it is now clear, far too many people and businesses did in the 2000s – they borrowed more from posterity than their innovation rate would support. They misallocated the resources to unproductive ends. Most past bursts of human prosperity have come to naught because they allocated too little money to innovation and too much to asset price inflation or to war, corruption, luxury and theft.

In the Spain of Charles V and Philip II, the gigantic wealth of the Peruvian silver mines was wasted. The same ‘curse of resources’ has afflicted countries with windfalls ever since, especially those with oil (Russia, Venezuela, Iraq, Nigeria) that end up run by rent-seeking autocrats. Despite their windfalls, such countries experience lower economic growth than countries that entirely lack resources but get busy trading and selling – Holland, Japan, Hong Kong, Singapore, Taiwan, South Korea. Even the Dutch, those epitomes of seventeenth-century enterprise, fell under the curse of resources in the late twentieth century when they found too much natural gas: the Dutch disease, they called it, as their inflated currency hurt their exporters. Japan spent the first half of the twentieth century jealously seeking to grab resources and ended up in ruins; it spent the second half of the century trading and selling without resources and ended up topping the lifespan league. In the 2000s the West misspent much of the cheap windfall of Chinese savings that the United States Federal Reserve sluiced our way.

So long as somebody allocates sufficient capital to innovation, then the credit crunch will not in the long run prevent the relentless upward march of human living standards. If you look at a graph of world per capita GDP, the Great Depression of the 1930s is just a dip in the slope. By 1939 even the worst-affected countries, America and Germany, were richer than they were in 1930. All sorts of new products and industries were born during the Depression: by 1937, 40 per cent of DuPont’s sales came from products that had not even existed before 1929, such as rayon, enamels and cellulose film. So growth will resume – unless prevented by the wrong policies. Somebody, somewhere, is still tweaking a piece of software, testing a new material, or transferring a gene that will make your and my life easier in the future. I cannot know who or where he is for sure, but let me give you a candidate. In the week I wrote this paragraph, a small company called Arcadia Biosciences in northern California signed an agreement with a charity working in Africa to license, royalty-free to smallholders, new varieties of rice that can be grown with less nitrogen fertiliser for the same yield, thanks to the over-expression in the roots of a version of a gene called alanine aminotransferase borrowed from barley. Assuming the varieties work in Africa as well as they do in California, some African will one day grow and sell more food (for less pollution), which in turn means that he will have more money to spend, earning the cost of, say, a mobile phone, which he will buy from a Western company, and which will help him find a better market for his rice. An employee of that Western company will get a pay rise, which she will spend on a new pair of jeans, which were made from cotton woven in a factory that employs the smallholder’s neighbour. And so on.

As long as new ideas can breed in this way, then human economic progress can continue. It may be only a year or two till world growth resumes after the current crisis, or it may for some countries be a lost decade. It may even be that parts of the world will be convulsed by a descent into autarky, authoritarianism and violence, as happened in the 1930s, and that a depression will cause a great war. But so long as somewhere somebody is incentivised to invent ways of serving others’ needs better, then the rational optimist must conclude that the betterment of human lives will eventually resume.
