It’s the MAIN reason that Ernst Rohm was killed in the Night of the Long Knives.
Rohm and most of the SA, were Communists in all but name, advocating a complete nationalization of all German industry. Hitler, realizing that he needed the industrialists on his side to build his war machine, had to off Rohm to placate the industrialists.
No doubt, that once the war was won, Hitler would have offed the Industrialists as a class, with as much vigor as the Jews.
That is true. Along with the industrialists, Hitler also had a deal with the military just before the Night of the Long Knives. After offing Rohm (who wanted to also lead the nationalized Brownshirts as Germany’s military), the military pledged complete loyalty to Hitler.
