"It is commonly agreed that Keynes came up with the idea that public works are the best way to help the economy during a recession. As a result, Keynesian economists seem to have developed a blind faith in the government in general, and in the system of public works in particular. I do not share the same faith in the government. I do not share the same faith in public works.And this may help explain why."
