Hitler's economic policies, if we're going to use the politicalcompass.org as a measuring stick, were pretty moderate. If anything, Bush is more rightwing when it comes to economic policies. What makes Hitler stand out is how authoritarian he was. He believed in the state more than the individual when it came to making decisions.
To be more precise, Hitler embodies what I would like to term "authoritarian corporate welfare." Another term could be "authoritarian corporatism." While he was not as rightwing as Bush is today with economic policy, he was not above total collaboration between the state and the corporation. Bush et al. are more subtle than that. This is why no one can claim that the state owns the media in the US. Corporations do instead. It's just that they have a very heavy influence on government at the same time, not the same as a true partnership or collaboration.
My signature gets more to the point though, but I think it's been disabled boardwide. It's a quotation of Mussolini stating that fascism should be redefined as corporatism because it is the merger of state and corporate power. That is it in a nutshell.
