After having read How Did Economists Get It So Wrong, How Did Paul Krugman Get It So Wrong, Leverage and Liberal Democracy and the Punch Bowl speech, summarize your views on the role of intervention in the financial markets focusing on the need for intervention, alternatives to regulatory regimes, the appropriate level of regulation and possible unintended consequences of intervention.

Address all three significant forms of interventions fiscal policy, monetary policy and regulatory policy.

In offering your viewpoint, state one way or the other if you are Freshwater (mostly laissez-faire) or Saltwater (mostly interventionist).  In other words, your discussion should not be situation dependent.  This will force you to solidify your arguments more concretely.
