Joseph Schumpeter and the Economics of Imperialism — John E. King

The Austrian economist Joseph Schumpeter believed that the triumph of socialism was inevitable, but he rejected the Marxist view of how capitalism works. His ideas are a stimulating challenge for those seeking an alternative to capitalism today....

Schumpeter was Austrian by birth and associated with members of what became the Austrian School as a student of Eugen von Böhm-Bawerk at the University of Vienna, but he did not identify himself with any school of economics and considered himself independent. Incidentally, Hyman Minsky was a student of Schumpeter and Randy Wray was a student of Minsky, so there is a link between the development of MMT and Schumpeter.
