Barack, we hardly knew ye'd be this bad

Brad DeLong should have listened to us, long ago. He then might have been able to avoid having to admit this;

A year and a half ago, when some of us were expecting a return to whatever the path of potential output was by 2017, our guess was that the Great Recession would wind up costing the North Atlantic in lost production about 80% of one year’s output–call it $13 trillion. Today a five-year return to whatever the new normal might be looks optimistic–and even that scenario carries us to $20 trillion. And a pessimistic scenario of five years that have been like 2012-2014 plus then five years of recovery would get us to a total lost-wealth cost of $35 trillion.

At some point we will have to stop calling this thing “The Great Recession” and start calling it “The Greater Depression”. When?

When DeLong votes for a Republican?  Hell freezes over?
