Like I said, I don't disagree with things sucking in general.

Perception is very important, though.
It would be possible to be perfectly depressed, even if things did not, in fact, suck.
But of course, it's a lot easier to be depressed and to believe, that everything sucks, if that is actually reflected in reality.

A big part of combatting depression, is to focus your perception on things, that don't suck and changing the ones that can be changed, to suck less; instead of making yourself sick by fussing about the things you cannot change anyway.

I struggle with that every day.

Do you mind sharing, what kind of changes those were and how they were important for you to feel better?

That explanation falls a bit short. While it surely explains a lot of people, it doesn't apply to everybody. There are definitely also people (some of whom I know personally) who are neither stupid & self-centered nor depressed.

I think, at least for Americans, they are absolutely brainwashed. They can't imagine a different world and think this is the Pinnacle of human existence. Then it turns out they are so EVIL they don't really care and ignore school children getting killed by guns and systematically raped by elites.
