Fascism is an economic system where corporations are dominated by the state and, ultimately, serve the state. Aren’t Google, fakebook, Amazon, and Twitter serving the state? And why? Because they are dominated by the state who has threatened them with unfavorable legislation. This is the real fascism. Imho.
Fascism is not an “economic system”.
It is a variant of Georges Sorel’s socialism that favors the overthrow of capitalism by means of force.
Mussolini was expelled from the Socialist Party for advocating the use of military force which Marxist socialism opposes.
First Lenin then Hitler adapted fascism to justify armed revolution.
Fascism like the syndicalist socialism it grew out of aims for the overthrow of capitalism, therefore the idea that capitalists are fascist is idiocy.
