I see that tragic poem of "first they came for" unfolding in real time
I see a nation who like you say, are beaten down
But I also see a society which celebrates being selfish, so I don't think you're capable of banding together, even when it's obvious that you should (ie. a few decades ago when Regan was in power)
It doesn't help that America is a deliberately stupid country
The typical American is desperate, struggling, frightened and beaten into apathy
Unfortunately, they're also incredibly poorly educated and ignorant.
What they're taught in school is a sanitised and propagandised version of the world, where America is always the hero
When they are shown how civilised countries operate, the response is always "this is America, we don't want that here, despite the fact that it's demonstrably better for everyone in society"
I'd say "the religious who want to inflict their superstitious idiocy on others", but I think you've already covered them with those two groups
