Not true. Read Goebbles biography or Hitlers speeches. Their agricultural system was 100% Marxist, as was their health care. The powerful central government and propaganda were as well.
Maybe you should go back and read those speeches again. Hitler railed against Marxists constantly. The Nazi party fought them in the streets, and actions are louder than words.
Their reforms were socialist, but not Marxist. That doesn’t mean they didn’t borrow anything from Marx, but they rejected many of the most fundamental points of his thinking and hated the other socialists who did not.
