I wouldn't call it "freedom from want," I think this is the disappointing part about the human condition, it's just that people start looking at outgroups well before they're comfortable. "Medieval peasant brain." Medieval peasants didn't have it particularly good.

only a peasant would have in/out group biases 🙃

not *only* a peasant: some (most?) people may have them but decline to make it their whole politics, other people don't have medieval peasant brain but are all in on the project.

Like, Stephen Miller: I don't think he fits in that category.

I'm saying comfort breeds paranoia, both about the continued persistence of said comfort and your own comfort relative to the comfort of others, which leads to reactionaries getting elected.

but clearly there's contrary effects, right? Desperation makes people pretty radical and nasty, too. Plus, I think there's an ethical obligation to try to improve material conditions for the many. I just don't expect a political payoff for the people that put it in place, it's quite chaotic.
