Peter Drucker

[T]he complete collapse of the belief in the attainability of freedom and equality through Marxism has forced Russia to travel the same road toward a totalitarian society of unfreedom and inequality which Germany has been following. Not that communism and fascism are essentially the same. Fascism is the stage reached after communism has proved an illusion, and it has proved as much an illusion in Russia as in pre-Hitler Germany.

Peter Drucker (1939), as cited in The Road to Serfdom (Condensed Edition, March 1944), by F.A. Hayek.
