“NAZI = National SOCIALIST Party.”
Nazi countenancing of ostensibly private businesses appears to be derived from Lenin’s New Economic Policy. It and Mussolini’s Fascism was a redesign of socialism to appeal to not only nationalism but also to those who were staunchly against state atheism, knowing what the USSR did to religions. And it was the USSR that started calling them “far right” in order to make a contrast with itself that nobody else could see aside from the obvious differences.
Hayek described what you are outlining in the 1940s:
Although our modern socialists’ promise of greater freedom is genuine and sincere, in recent years observer after observer has been impressed by the unforeseen consequences of socialism, the extraordinary similarity in many respects of the conditions under “communism” and “fascism.” As the writer Peter Drucker expressed it in 1939, “the complete collapse of the belief in the attainability of freedom and equality through Marxism has forced Russia to travel the same road toward a totalitarian society of un-freedom and inequality which Germany has been following. Not that communism and fascism are essentially the same. Fascism is the stage reached after communism has proved an illusion, and it has proved as much an illusion in Russia as in pre-Hitler Germany.”
No less significant is the intellectual outlook of the rank and file in the communist and fascist movements in Germany before 1933. The relative ease with which a young communist could be converted into a Nazi or vice versa was well known, best of all to the propagandists of the two parties. The communists and Nazis clashed more frequently with each other than with other parties simply because they competed for the same type of mind and reserved for each other the hatred of the heretic. Their practice showed how closely they are related. To both, the real enemy, the man with whom they had nothing in common, was the liberal of the old type. While to the Nazi the communist and to the communist the Nazi, and to both the socialist, are potential recruits made of the right timber, they both know that there can be no compromise between them and those who really believe in individual freedom.
