Time for a different kind of economist?

If I had Obama's ear, I would tell him that since Summers is leaving, pull in someone like Krugman, Roubini or Stiglitz. Summers and Geithner got us through the economic armageddon--it was probably smart to have people trusted by Wall Street at that point, but maybe it is time for some experts who don't trust Wall Street. After all, Wall Street is responsible for the economic debacle, but is yet to feel much of a pinch in the way of new regulations. We still have companies that are too big to fail. We still have massive foreclosures. We still have derivatives whose quality is hidden.
