The U.S. public still has faith in capitalism, says NYU economics professor Nouriel Roubini. "One of the lessons of the financial crisis is that the public also grudgingly realizes that prudential government intervention, at least in the regulation and supervision of the financial system, might be necessary. There isn’t a wholesale rejection of capitalism, but I think there was a greater faith 10 years ago in an unfettered, laissez-faire market economy."
