We have a reaction to moral hazard, due to government interference into the markets. As a result, crisis prevention is necessary via government intervention; as they caused the mess in the first place. Throughout the 20th century, at least 5 economic crisis's have arisen that have been "solved", and as always another has followed with remnants of the past. Crisis is much different than recession.

What i am saying is, fault must be placed on many individuals throughout many administrations to effectively identify the culprits, starting with the federal reserve. Being as they have been and still are used as an economic bailout facility for over 80 years, investors are more inclined to make riskier moves due to a governmental floor in the form of various bailouts.
