No the Nazis did not do central economic planning and the USSR did not believe the strong should rule the weak nor did they believe in creating a “master race” by exterminating the perceived other and before you say much GuLaGs a Gulag is a prison in which you serve time by working, similar to private prisons in the US however it wasn’t done on the basis of exchange value but labour time.
Central economic planning is what socialism is about to solve the crisis of over production doing away with the profit motive.
