The US hasn't had capitalism in the classical sense for, well, my entire life. What we have now could be called, perhaps, corporatism. There is a decided marriage of the state and the corporation such that true competition doesn't exist except at the small, local level. Oligopoly, that's the word I'm looking for. I think a political economist would politely describe us as a "mixed economy." There is a shift in economic thought here such that decision making processes take into account long-term realities rather than just quarterly profit margins, though many industries have hardly taken note. We are barely surviving our second bad case of "voodoo economics" under Bush II. Pretty much anything is going to be an improvement.
I would seriously dispute that. Yes, the corporations are powerful. Oligopoly is a fitting term. Corporatism...not so much. Corporatism, fascism, there's no time to explain that now. What I shall say is that the method of exchange, the way in which people act, consume etc. is still largely capitalist. That is what defines social relations. That is where anomie comes from.
