Hitler did not have Mussolini's revolutionary socialist background... Nevertheless, he shared the socialist hatred and contempt for the 'bourgeoisie' and 'capitalism' and exploited for his purposes the powerful socialist traditions of Germany. The adjectives 'socialist' and 'worker' in the official name of Hitler's party ('The Nationalist-Socialist German Workers' Party') had not merely propagandistic value... On one occasion, in the midst of World War II, Hitler even declared that 'basically National Socialism and Marxism are the same.'
