Really? The point I’m touching on, about cultural hegemony, was the product of Antonio Gramsci’s thought, who was a Marxist prisoner under Mussolini’s fascist regime. The rest is Marx’s criticism of the bourgeois class.
If you read Mein Kampf, Hitler repeatedly speaks to his hatred of Marxism, which he denounces as Jewry. He says society would collapse with the implementation of Marxian ideas. I can mine an exact quote for you, if you like.
The Nazis weren’t socialists but they pandered to the working class in the countryside in Germany to build a following, and slowly win local elections. Eventually, the political right in Germany would abandon the numerous splinter parties for the NSDAP, and the Nazis would be the most prominent Conservative Party in Germany.
