Here are ten reasons why:
I. Knowledge
Government policies suffer from the pretense of knowledge . In order to perform a successful market intervention, politicians need to know more than they can. Market knowledge is not centralized, systematic, organized and general, but dispersed, heterogeneous, specific, and individual. Different from a market economy where there are many operators and a constant process of trial and error, the correction of government errors is limited because the government is a monopoly. For the politician, to admit an error is often worse than sticking with a wrong decision – even against own insight.
