Here's a good excerpt from Thomas Sowell's column of January 30th:
. . . There is a vast difference between what the government could do and what it is likely to do.
Economists can give you all sorts of scenarios in which government intervention could make things better, whether when fighting off a recession, regulating domestic markets or controlling international trade.
Some people even believe that whenever there is "market failure," the government ought to step in.
Of course markets can fail. Everything human can fail. But if Alex Rodriguez strikes out, do the Yankees take him out of the game and send in a pinch hitter for him?
No one would dream of suggesting such a thing. We are far more rational when discussing sports than when discussing politics.
The fact that the market is not doing what we wish it would do is no reason to automatically assume that the government would do better.
