This newspaper reported recently that Bill Gates hates my ideas. I have no hurt feelings, at least nothing that months of intensive psychotherapy can't cure. Mr. Gates, after all, has allied himself with the foreign aid establishment. This establishment is notoriously sensitive to criticism from people like me, who find no evidence that the aid industry's grand schemes are actually lifting anyone out of poverty.

Mr. Gates has now put forward his own scheme -- "creative capitalism" -- in a speech at the recent World Economic Forum in Davos. He argues that today's capitalism does not benefit the poor. For Mr. Gates, regular capitalism works "only on behalf of those who can pay." While entrepreneurs fall all over themselves trying to meet the needs of the rich, "the financial incentive to serve [the poor is] zero." As a result, basic needs such as food and medicine go unmet.

Mr. Gates seems to believe that the solution is to persuade for-profit companies to meet the poor's needs by boosting the "recognition" of corporate philanthropy. But the dossier of historical evidence to suggest this would work is as thin as Kate Moss on a diet. First of all, the recognition motive has proven to be awfully weak compared to the profit motive. Otherwise we would have had a lot more than the $5.1 billion of annual American corporate philanthropy to the Third World (as of 2005, which has the most recent reliable figures). That was four one-hundredths of 1% of the $12.4 trillion of U.S. production for the free market. Is it really the poor's only hope that the Gap will donate a few pennies per sexy T-shirt for AIDS treatment in Africa?

Profit-motivated capitalism, on the other hand, has done wonders for poor workers. Self-interested capitalist factory owners buy machines that increase production, and thus profits. Capitalists search for technological breakthroughs that make it possible to get more output for the same amount of input. Working with more machinery and better technology, workers produce more output per hour. In a competitive labor market, the demand for these more productive workers increases, driving up their wages. The steady increase in wages for unskilled labor lifts the workers out of poverty.

The number of poor people who can't afford food for their children is a lot smaller than it used to be -- thanks to capitalism. Capitalism didn't create malnutrition, it reduced it. The globalization of capitalism from 1950 to the present has increased annual average income in the world to $7,000 from $2,000. Contrary to popular legend, poor countries grew at about the same rate as the rich ones. This growth gave us the greatest mass exit from poverty in world history.
