The Global Poverty Trap

It's nature vs. nurture. One of the big debates of our time involves the causes of economic growth. Why is North America richer than South America? Why is Africa poor and Europe wealthy? Is it possible to eliminate global poverty? The World Bank estimates that 2.5 billion people still live on $2 a day or less. On one side are economists who argue that societies can nurture economic growth by adopting sound policies. Not so, say other scholars such as Lawrence Harrison of Tufts University. Culture (a.k.a. "nature") predisposes some societies to rapid growth and others to poverty or meager growth.

Comes now Gregory Clark, an economist who interestingly takes the side of culture. In an important new book, " A Farewell to Alms: A Brief Economic History of the World," Clark suggests that much of the world's remaining poverty is semi-permanent. Modern technology and management are widely available, but many societies can't take advantage because their values and social organization are antagonistic. Prescribing economically sensible policies (open markets, secure property rights, sound money) can't overcome this bedrock resistance.

"There is no simple economic medicine that will guarantee growth, and even complicated economic surgery offers no clear prospect of relief for societies afflicted with poverty," he writes. Various forms of foreign assistance "may disappear into the pockets of Western consultants and the corrupt rulers of these societies." Because some societies encourage growth and some don't, the gap between the richest nations and the poorest is actually greater today (50 to 1) than in 1800 (4 to 1), Clark estimates.

All this disputes the notion that relentless globalization will inevitably defeat global poverty. To Clark, who teaches at the University of California, Davis, history's most important event was the Industrial Revolution—more important than the emergence of monotheism, which produced Judaism, Christianity and Islam; or the invention of the printing press around 1450, which spread knowledge, or the American Revolution, which promoted democracy.

Before 1800, says Clark, most societies were stagnant. With some exceptions, people lived no better than their ancestors in the Stone Age. Economic growth was virtually nonexistent. Then England broke the pattern, as textile, iron and food production increased dramatically. Since 1800, English income per person has risen by a factor of 10. Much of Europe and the United States followed.

Almost everything that differentiates the modern era from the preceding millennia dates from this point: the virtual end of hunger in advanced societies; the expectation that living standards will constantly rise; the creation of the welfare state to redistribute income; the destructiveness of contemporary warfare; industry's environmental spoilage. But why did the Industrial Revolution start in England?
