Under communism (socialism), there is no incentive to supply people with anything they need or want, including safety. - George Reisman

Private ownership of the means of production existed in name only under the Nazis and that the actual substance of ownership of the means of production resided in the German government. For it was the German government and not the nominal private owners that exercised all of the substantive powers of ownership: it, not the nominal private owners, decided what was to be produced, in what quantity, by what methods, and to whom it was to be distributed, as well as what prices would be charged and what wages would be paid, and what dividends or other income the nominal private owners would be permitted to receive.

When one remembers that the word "Nazi" was an abbreviation for "der Nationalsozialistische Deutsche Arbeiters Partei" — in English translation: the National Socialist German Workers' Party — Mises's identification might not appear all that noteworthy. For what should one expect the economic system of a country ruled by a party with "socialist" in its name to be but socialism?

What specifically established de facto socialism in Nazi Germany was the introduction of price and wage controls in 1936.
