I've read Ferguson, and I like him.
Frankly, I feel as if I benefit from living in the world's hegemon, and I believe that I, and the average American, would be worse off if we were to lose that status. So I think it has been a good thing, economically, politically, and militarily.
Culturally, it's a different story. Perhaps it's because the US lacks any sort of high culture or really a kind of native culture, Americanization has been the worst thing to happen to the world, and I say this without hyperbole, in the past 150 years. The wholesale standardization of societies and decimation of traditional cultures is just... indescribably terrible. When
I see it happen to my own culture it makes my blood boil. I mean, the whole idea of substantive, and meaningful differences between peoples is quaint nowadays, because we're all the same, fed the rubbish that comes out of this country. Coca-Cola was cute as something similar everywhere. But this is different. It's just... disgusting.
