THE last 20 years have brought the world more trade, more globalization and more economic growth than in any previous such period in history. Few commentators had believed that such a rise in trade and living standards was possible so quickly.

More than 400 million Chinese climbed out of poverty between 1990 and 2004, according to the World Bank. India has become a rapidly growing economy, the middle class in Brazil and Mexico is flourishing, and recent successes of Ghana and Tanzania show that parts of Africa may be turning the corner as well.

Despite these enormous advances, however, there is a backlash against globalization and a widespread belief that it requires moderation. Ordinary people often question the benefits of international trade, and now many intellectuals are turning more skeptical, too. Yet the facts on the ground show that the current climate of economic doom and gloom simply isn’t warranted. The classic economic recipes of trade, investment and good incentives have never been more successful in generating huge gains in human welfare.

The globalization process has had its bumps, of course, as reflected recently by rising commodity prices, but that is largely a consequence of how much and how rapidly prosperity has grown. Countries like China have become richer so fast that global production of energy and food have been unable to match the pace. But rapid economic growth is the right direction, even if some of the remaining poor are suffering from high food prices.
