Russia did allow some private enterprise...see the “New Economic Policy”.
The Nazis could nationalize anything they wanted to on a whim, just as the Communists could, but would at times allow private enterprise, when it benefited them.
Stalin put an end to NEP by 1928 or 1929, from then on there would be no private enterprise in the Soviet Union until the last years of Gorbachev.

They certainly had the power to do so, but in general they didn't. Virtually no industries were nationalized by the Nazis - factories remained in private hands. Even banks remained nominally private. The only property that was consistently confiscated by the state was the property of Jews and other "non-Germans."
The point is that the German aristocracy, along bankers and industrialists could happily coexist with the Nazi government. They wouldn't be able to do so under Communist rule, which is why they threw their support behind what they perceived to be the lesser evil in the 1930's.
