I've mentioned this before to others whenever this comes up. most or a great majority of people in the US have it "good enough" to not "risk it all".
Things over here "aren't bad enough" for people to full-on revolt. I'd say we're kinda close but modern, white, boring america just doesn't want to get caught in the shit storm. They understand it might come for them at some point but that time isn't now so why "stick their neck out"
