Hitler only tolerated Capitalism to the extent that it helped him to build his war machine. Once the war was won, he planned to eliminate the “business class”.
People who have this fanatical need to attach labels to Hitler tie themselves into pretzels for no reason.
Hitler is not a Left/Right issue. But people on the left push the "Hitler is right-wing" myth and people on the Right feel like they must defend themselves by pushing the "Hitler is a socialist" myth.
Hitler transcends "Left/Right" labels. He is a demonic tyrant, first and last.
