So now we see, at last, that the business cycle is brought about, not by any mysterious failings of the free market economy, but quite the opposite: By systematic intervention by government in the market process. Government intervention brings about bank expansion and inflation, and, when the inflation comes to an end, the subsequent depression-adjustment comes into play... what the government should do, according to the Misesian analysis of the depression, is absolutely nothing. It should, from the point of view of economic health and ending the depression as quickly as possible, maintain a strict hands off, "laissez-faire" policy. Anything it does will delay and obstruct the adjustment process of the market; the less it does, the more rapidly will the market adjustment process do its work, and sound economic recovery ensue. The Misesian prescription is thus the exact opposite of the Keynesian: It is for the government to keep absolute hands off the economy and to confine itself to stopping its own inflation and to cutting its own budget.
