There was an engineer in the early 1900s who thought he solved capitalism, he made a whole ass system called Social Credit - this was in response to the manifest failures of capitalism but refusal to take any of Marxism seriously prima facie.

It never went very far, except in my home province of Alberta which seems to be the playground of whatever stupid ass ideas the national bourgeoisie (instead of international big bourgeoisie) think is neat at the moment.
