Keynes was not an economist. He was a fantasist. Did you ever read him? In classes where he is taught his paragraphs are read for the firs line and the conclusion. Everything in between is nonsensical. Most does not cohere as English and meaning can only be assumed or speculated. It reads like a poorly done MIT paper designed to be accepted in prestigious journals then to be jeeringly outed by the authors as a fraud.
I mention Keynes as beltway folk seem to make him their god, of course most of them are too dumb to know anything about economics of any kind, they only listen to "brilliant minds" like Paul Krugmann.
