The biggest difference between the two is over how production is controlled.
Communism runs business directly from the central committee and it fails primarily due to the overwhelming nature of the task and because of inherent government inefficiency and corruption.
Nazism used the existing corporate/business structure and personnel and just ordered them to achieve the results the hierarchy wanted. This is a much stronger economic system than communism (which is the worst system imaginable) but will always fail eventually because it is totalitarian.
What Obama was doing is extremely close to how fascism (Nazism = fascism + nationalism) operated in practice. The Obama/Clinton version was being called corporatism to mask its true identity.
