re: Dictatorship of the Middle Class.
Wouldn't be "middle class" for long.
The main examples of fascist societies, Germany and Italy, existed in their mature form for less than 20 years. Had they survived, the centralized authoritarian power structure over both the economy and political activity would have rotted both nations into the Third World style typical of long-term Communist societies.
At bottom, despite the protests of both Nazis and Communists, there is really no difference between the two philosophies.
