People on the right tend to use “Keynesian” to mean “liberal stuff I don’t like”, but aside from that definition, the 70s tell us nothing about the issues we’re discussing right now. You can argue that monetary policy was too loose, that the Fed was too expansionary in 1972 (when Arthur Burns was trying to reelect Richard Nixon) and that it failed to tighten in the face of oil-shock-driven inflation. But again, the idea that this experience has any relevance to expansionary fiscal policy in the face of a liquidity trap is totally bogus.
Worth a read.
