A Keynesian would suggest government intervention during a recession to inject spending into the economy when people are not. However, the heart of Austrian macroeconomic theory states the government "fine tuning" through expansions and contractions in the money supply orchestrated by the government are actually the cause of business cycles because of the differing impact of the resulting interest rate changes on different stages in the structure of production. Austrian economist Thomas Woods further supports this view by arguing it is not consumption, but rather production that should be emphasized. A country cannot become rich by consuming, and therefore, by using up all their resources. Instead, production is what enables consumption as a possibility in the first place, since a producer would not be working for nothing, if not for the desire to consume.
