Is it cruel to point out that when Paul Krugman says that an alien invasion would save Keynesianism…

…he’s pretty much cribbing off of Reagan’s observation that an alien invasion would unite humanity and war among us?

Or is it just sad that Krugman comes across as profoundly intellectually stunted, in comparison?  I mean, if we’re going to have an alien invasion serve a higher purpose then I’d personally prefer a more meaningful one than salvaging a somewhat dunderheaded liberal economic theory.
