As I said before, I agree with your main point that thus far the US business has no need for fascism yet, because it gets want it wants through liberal democratic means. I do not think, however, that this will continue indefinitely. The business class ambition of power grow exponentially with the past successes to get their way, but sooner or later they will be thwarted - by the ruling classes of other countries (China? India? United Europe?), a popular movement, an environmental catastrophe, or perhaps a combination thereof. And when such a moment arrives, fascism may look like a desirable option to the US business elite.
