There are sociological developments happening that cannot be changed by policies or institutions. People have increasingly abandoned the institutions and organizations that provide meaning in life. People under a certain age increasingly go from sterile, fleeting, empty relationships in quick succession, growing older and growing unhappier as the consequences of this lifestyle become clear. Politics offers an easily accessible means by which to assert truths and fashion a moral identity.
You're a fool if you think a particular party or politician can mend these sorts of things. Not every problem has a solution. Just accept it and carve out as nice an existence as you can in your small corner of the world. I would also recommend turning off the news more and more. I used to mock people when they said this. Now I see the value in doing this. As people around me grew more and more angry/depressed/anxious over the past couple years, I started to get feedback that I seemed more relaxed than they'd seen me. I think a big part of it was that I gradually stopped paying attention to the nonsense. I still don't really know what the "Steele Dossier" entailed. Jim kept throwing the term, "QAnon" at me, and it wasn't until about three weeks ago that I finally found out, kind of, what it means, from a family member. I couldn't care less. I'll pay attention to the cultural stuff, and I'll pay attention when the Biden Administration and all the foreign policy retreads and ghouls push us towards another war, but most of this stuff simply doesn't interest me anymore. You'll be surprised how quickly you start losing interest, too.
