The nsdap had a left, socialist wing. Most of the members of that wing were executed, which is a good indicatior on how much Hitler himself agreed with them. He himself didn't had many political views one could describe as left, that there are similarities in the methods is mainly a coincidence. Your linked article is plainly wrong in that regard, the nationalization of industries for example didn't really happen after the Kapital agreed to cooperate (and ideologically, nationalization of industries in a facist regime is something else entirely than in a communist one).
For a good article about the subject, read http://www.h-ref.de/organisationen/nsdap/nazis-sozialisten.p.... Anyway, I don't think we should discuss this any further here, it is OT.
