Karl Rove jabs John McCain

This past Thursday, Mr. McCain came close to advocating a form of industrial policy, saying, "I'm very angry, frankly, at the oil companies not only because of the obscene profits they've made, but their failure to invest in alternate energy."

Mr. McCain's angry statement shows a lack of understanding of the insights of Joseph Schumpeter, the 20th century economist who explained that capitalism is inherently unstable because a "perennial gale of creative destruction" is brought on by entrepreneurs who create new goods, markets and processes. The entrepreneur is "the pivot on which everything turns," Schumpeter argued, and "proceeds by competitively destroying old businesses."

Most dramatic change comes from new businesses, not old ones. Buggy whip makers did not create the auto industry. Railroads didn't create the airplane. Even when established industries help create new ones, old-line firms are often not as nimble as new ones. IBM helped give rise to personal computers, but didn't see the importance of software and ceded that part of the business to young upstarts who founded Microsoft.

Messrs. Obama and McCain both reveal a disturbing animus toward free markets and success. It is uncalled for and self-defeating for presidential candidates to demonize American companies. It is understandable that Mr. Obama, the most liberal member of the Senate, would endorse reckless policies that are the DNA of the party he leads. But Mr. McCain, a self-described Reagan Republican, should know better.
