Here is a very good response to this by /u/kieslowskifan. Essentially, the Nazis didn't really criticize capitalism in so much as we traditionally understand it. Instead, their critiques of capitalism had a racial character and also played off the disenchantment with the economy in the after math of the war and the crash. Their actual policies were not in any way substantially anti-capitalist and were actually some of the first examples of privatization as government policy.
