The Formula for a Richer World? Equality, Liberty, Justice

NYT’s:

The world is rich and will become still richer. Quit worrying.

Not all of us are rich yet, of course. A billion or so people on the planet drag along on the equivalent of $3 a day or less. But as recently as 1800, almost everybody did.

The Great Enrichment began in 17th-century Holland. By the 18th century, it had moved to England, Scotland and the American colonies, and now it has spread to much of the rest of the world.

Economists and historians agree on its startling magnitude: By 2010, the average daily income in a wide range of countries, including Japan, the United States, Botswana and Brazil, had soared 1,000 to 3,000 percent over the levels of 1800. People moved from tents and mud huts to split-levels and city condominiums, from waterborne diseases to 80-year life spans, from ignorance to literacy.

You might think the rich have become richer and the poor even poorer. But by the standard of basic comfort in essentials, the poorest people on the planet have gained the most. In places like Ireland, Singapore, Finland and Italy, even people who are relatively poor have adequate food, education, lodging and medical care — none of which their ancestors had. Not remotely.

Inequality of financial wealth goes up and down, but over the long term it has been reduced. Financial inequality was greater in 1800 and 1900 than it is now, as even the French economist Thomas Piketty has acknowledged. By the more important standard of basic comfort in consumption, inequality within and between countries has fallen nearly continuously.

In any case, the problem is poverty, not inequality as such — not how many yachts the L’Oréal heiress Liliane Bettencourt has, but whether the average Frenchwoman has enough to eat. At the time of “Les Misérables,” she didn’t. In the last 40 years, the World Bank estimates, the proportion of the population living on an appalling $1 or $2 a day has halved. Paul Collier, an Oxford economist, urges us to help the“bottom billion” of the more than seven billion people on earth. Of course. It is our duty. But he notes that 50 years ago, four billion out of five billion people lived in such miserable conditions. In 1800, it was 95 percent of one billion.

We can improve the conditions of the working class. Raising low productivity by enabling human creativity is what has mainly worked. By contrast, taking from the rich and giving to the poor helps only a little — and anyway expropriation is a one-time trick. Enrichment from market-tested betterment will go on and on and, over the next century or so, will bring comfort in essentials to virtually everyone on the planet, and more to an expanding middle class.
