Question

An American earns, on average, $130 a day, which puts the U.S. in the highest rank of the league table. China sits at $20 a day (in real, purchasing-power adjusted income) and India at $10, even after their emergence in recent decades from a crippling socialism of $1 a day. After a few more generations of economic betterment, tested in trade, they will be rich, too.

Actually, the “we” of comparative enrichment includes most countries nowadays, with sad exceptions. Two centuries ago, the average world income per human (in present-day prices) was about $3 a day. It had been so since we lived in caves. Now it is $33 a day—which is Brazil’s current level and the level of the U.S. in 1940. Over the past 200 years, the average real income per person—including even such present-day tragedies as Chad and North Korea—has grown by a factor of 10. It is stunning. In countries that adopted trade and economic betterment wholeheartedly, like Japan, Sweden and the U.S., it is more like a factor of 30—even more stunning.

And these figures don’t take into account the radical improvement since 1800 in commonly available goods and services. Today’s concerns over the stagnation of real wages in the U.S. and other developed economies are overblown if put in historical perspective. As the economists Donald Boudreaux and Mark Perry have argued in these pages, the official figures don’t take account of the real benefits of our astonishing material progress.

Look at the magnificent plenty on the shelves of supermarkets and shopping malls. Consider the magical devices for communication and entertainment now available even to people of modest means. Do you know someone who is clinically depressed? She can find help today with a range of effective drugs, none of which were available to the billionaire Howard Hughes in his despair. Had a hip joint replaced? In 1980, the operation was crudely experimental.

Nothing like the Great Enrichment of the past two centuries had ever happened before. Doublings of income—mere 100% betterments in the human condition—had happened often, during the glory of Greece and the grandeur of Rome, in Song China and Mughal India. But people soon fell back to the miserable routine of Afghanistan’s income nowadays, $3 or worse. A revolutionary betterment of 10,000%, taking into account everything from canned goods to antidepressants, was out of the question. Until it happened.

What caused it? The usual explanations follow ideology. On the left, from Marx onward, the key is said to be exploitation. Capitalists after 1800 seized surplus value from their workers and invested it in dark, satanic mills. On the right, from the blessed Adam Smith onward, the trick was thought to be savings. The wild Highlanders could become as rich as the Dutch—“the highest degree of opulence,” as Smith put it in 1776—if they would merely save enough to accumulate capital (and stop stealing cattle from one another).
