For every Milton Friedman who knows his stuff, seems like there are a thousand Keynesian know nothings.
I had a prof who was a Keynesian know nothing and preached a theory called the "Phillips Curve" during the Carter years to explain why both inflation and unemployment would increase simultaneously and indefinitely.
The only solution was for us to accept a lower standard of living. If that sounds familiar, just google Carter's "Malaise" speech.
Not long after Reagan came to office, the Phillips Curve theory, as it was originally preached, mysteriously dropped into a "memory hole."

Well, maybe, but the protectionists on FR and other Trumpistas aren’t usually Keynesians. Mostly they are just old-fashioned mercantilists.
