The article evaluates Keynes's General Theory, focusing on the problem of involuntary unemployment. It argues that the theory fails to address a non-existent problem, as involuntary unemployment is not a real issue. The researchers use extensive quotes from Keynes's work to support their claims. They highlight that deficit spending is not significant in the theory and that the concept of involuntary unemployment as defined by Keynes is impossible to prove, undermining the idea of full employment not existing.
