I'm aware that the "national socialist" (Nazi) party was by most accounts only socialist in name, e.g.:
Unfortunately for [Otto Strasser], he had taken seriously not only the word “socialist” but the word “workers” in the party’s official name of National Socialist German Workers’ Party. He had supported certain strikes of the socialist trade unions and demanded that the party come out for nationalization of industry. This of course was heresy to Hitler, who accused Otto Strasser of professing the cardinal sins of “democracy and liberalism.” On May 21 and 22, 1930, the Fuehrer had a showdown with his rebellious subordinate and demanded complete submission. When Otto refused, he was booted out of the party.
Likewise, two German economic historians write that
There occurred hardly any nationalizations of formerly private firms during the Third Reich. In addition, there were not very many enterprises newly created as state-run firms either. The most spectacular exception to that rule was the Reichswerke Hermann Göring which was founded in 1937 for the exploitation of the German bad-quality iron ore deposits. [...]
On the contrary the reprivatization of enterprises was furthered wherever possible. In the prewar period that was the case for example with the big German banks which had to be saved during the banking crisis of 1931 by the injection of large sums of public funds. In 1936/37 the capital of the Deutsche Bank, Commerzbank and Dresdner Bank in the possession of the German Reich was sold to private shareholders and consequently the state representatives withdrew from the board of these banks. Also in 1936 the Reich sold its shares of Vereinigte Stahlwerke. The war did not change anything with regard to this attitude. In 1940 the Genshagen airplane engine plant operated by Daimler-Benz was privatized; Daimler-Benz bought the majority of shares held by the Reich earlier than it wished to.
I'm curious however if the Nazi regime resorted to any nationalizations, for example, of Jewish assets. (And if they did so, did the Nazi then followed the pattern suggested above by "reprivatizing" such assets to "Aryan" private owners?)
