Krugman, a Nobel-prize winning economist, is the author of The Return of Depression Economics (W.W. Norton and Company; 2000) and a large body of work that is most frequently ignored by President Obama's economic team.
From Krugman on Plutocrats and Occupy Wall Street:
It remains to be seen whether the Occupy Wall Street protests will change America’s direction. Yet the protests have already elicited a remarkably hysterical reaction from Wall Street, the super-rich in general, and politicians and pundits who reliably serve the interests of the wealthiest hundredth of a percent.
And this reaction tells you something important — namely, that the extremists threatening American values are what F.D.R. called “economic royalists,” not the people camping in Zuccotti Park.
