(On edit: Oops. The post I was referring to isn't yours. I'll leave the point as is, but please recognize the correction).
since your point was that this White House seems to have more in common with fascists than Marxists, I'll discuss only fascism.
Fascism revolves around a corporatist state model. That term derives from corpus, the Latin word for body. It does not mean dominance by big business, as some mistakenly argue. Corporatism imagines the state as a single living organism. Labor, industrialists, and other sectors of society are incorporated through official government institutions that grant they certain benefits in exchange for loyalty to the state and, in the case of unions, an agreement to refrain from more radical labor activism. Corporatism emerged in the 1930s and 1940s in Europe and Latin America as a response to more radical, socialist and anarchist labor movements that sought workers' control of the means of production and of the state itself. Corporatism sought to incorporate those elements into the structure of the state itself by balancing labor and business interests in pursuit of a nationalist goal. The Bush administration displays no such attempt at balance. Big business clearly dominates, especially those chosen businesses with connections to the White House.
National socialism hinged on a corporatist state model. This country accepts no such view of the power of importance of labor or any other sector other than large campaign donors, big business.
Some point to the imperial aspirations of Hitler and Mussolini to suggest that this administration is fascist. There have been many kinds of empires in history. Ours is a naked capitalist empire. It promotes American power and the spread of US economic dominance. Imperial designs and repression of dissent have characterized many governments throughout history. Authoritarianism takes on many forms. Fascism was a particular kind of state that is not mirrored in the actions or aspiration of the Bush administration.
