What differentiates fascism from classical capitalism is of course its de-emphasis on class conflict. But this, in my opinion, really only marks a change in the overt propaganda of capitalism. It is capitalism without the velvet gloves. There is no change in behavior with regards to class conflict, but there is a change in mindset and vocabulary. National unity is sought, and ideas are sold as being "for the best for the country" and talk about "setting aside differences to get things done" is made, but what it really means is that the ruling class seeks a rhetorical and "moral" solution to their political obstacles. That is, they appeal to the nationalism of the citizenry to rally behind them and their "best" solution for everyone, which is in reality a solution only for them.
This is in stark contrast to the old style of political capitalism, which was wholly unashamed about its class conflict. The ruling class knew what was best, and deserved everything it had. End of story. They were better than the working class, in the same way that Khan Noonien Singh was better than most people. They sought a worthy adversary, tangling with the working class wasn't worth their time. One can still find traces of this rhetoric in politics today, from the looser-lipped of the oligarchs. But while these people tend to attract the most ire from liberals, I know that they are the more foolish and stupid of the capitalists. The real dangers are people like Bill Gates, who despite robbing half the world blind, is hailed as a saint for his "philanthropic efforts." They give back with one hand what they took with the other, rather like Starbucks and its involuntary donations "every dollar you spend sends a dime to starving children in Guatemala" or some crap like that.
A keen reader will note the similarities in the above with the recent tone of political discourse in American politics.
