Hitler hated communists not because of their economic doctrines, or because they wanted to destroy the bourgeoisie – he liked those notions. He championed trade unions in Mein Kampf, and attacked the greed and ‘short-sighted narrow-mindedness’ of businessmen as fervently as any modern anti-capitalist. No, he hated communism because he thought it was a foreign, Jewish conspiracy, as he made clear throughout Mein Kampf.
