Some real Keynesians would be a good thing compared to the garbage of today. Keynes wouldn’t spend like this, and he would be trying to balance the budget. The R’s and D’s who have been running up the debt are on a different level.
That’s why I call them Keystone Keynesians ... after Keystone Cops, not the beer.
Anyhoo, I consider it Keynes’ biggest failure that he never understood that once real world politicians (aka nitwits) got hold of his ideas that sooner or later all they’d ever have learned from him is an excuse to spend freely.
I will even go so far to say that Hayek had fewer fans because there was no spend to win ideology waiting in the wings, making his ideas inherently less attractive to real world politicians.
