The presidential candidates have been repeatedly asked how they would "manage the economy." With the exception of Ron Paul, every candidate has accepted the premise that this is something the president of the United States should do.

Or can do.

Nonsense.

Democrats act like the president is national economic manager. Republicans pay lip service to free markets, tax and spending cuts, and less regulation -- before proposing big programs to achieve "energy independence," job training and a cooler climate.

John McCain says it's important for government to do something "to sustain our leadership in manufacturing". Why? Manufacturing jobs are no better for America than other jobs. Some argue that they are worse. How many parents want their children to work in factories rather than offices? Increasing service jobs in medical, financial and computer sectors while importing manufactured goods doesn't hurt America. It helps America.

The candidates see the global economy as an arena in which countries compete against one another -- an economic Olympiad with winners and losers. Politicians love to promise they will keep America No. 1, as if that matters in a worldwide marketplace.

America as a nation does not compete against China or South Korea or Japan. American companies compete against companies in other countries, but that's something else. The purpose of production is consumption, and American consumers prosper when foreigners compete successfully with American companies.

A president who sees the global economy as a competition among nations will be tempted to intervene on behalf of the "United States" and create "good American jobs." That's how governments mess up economies.

McCain says, "It is government's job to help workers get the education and training they need for the new jobs". Mike Huckabee (who glories in public-works projects as a job-creation machine) and Barack Obama talk in similar terms.

That hardly shows confidence in the free market, which, if allowed, would train and educate workers just fine. But it shows misplaced confidence in the federal government, which, as journalist Jim Bovard has shown, has an unbelievably bad track record at doing it. The endless list of programs, like the Manpower Development and Training Administration, Comprehensive Employment and Training Act, Job Training Partnership Act, STIP, BEST, YIEPP, YACC, SCSEP, HIRE, etc., wasted billions and "distorted people's lives and careers by making false promises, leading them to believe that a year or two in this or that program was the key to the future. Federal training programs have tended to place people in low-paying jobs, if trainees got jobs at all." . Continued...
