Mein Kampf is full of Socialist rhetoric, and Hitler introduced old age pensions, unemployment payments and government work schemes. He created Volswagon to churn out affordable People's Cars. Germany under Hitler still had private ownership of most businesses, but the State had control of the centrally planned economy. As central Planning doesn't work as well as the free market, this contributed to his defeat, but central planning is core to a Socialist Government. If it walks like a Socialist and talks like a Socialist, it is probably a Socialist.
