A critical point here - blaming our regulatory system for the failings of Wall Street is duplicitous. Regardless of the degree of corruption within the business practices of all aspects of the Bush regime Wall Street is responsible for its actions - for self regulating itself.
Wall Street needs to pay, not just civilly with every dime they stole until it puts them on the streets, but also criminally. That needs to happen now, else Obama is just another crook.
