i saw this somewhere else on lemmy and i think it applies here: people lived rich and fulfilling lives despite the roman empire actively collapsing all around them.
we're getting more farcical for a myriad of reasons, but chief among them are the cool aide drinking and the willful ignorance against learning why things are fucked.
it takes time and effort to read and understand something like theory and that guarantees that the people who don't bother will vastly outnumber everyone else, so asshatery like you're seeing is a part of life (for now). the stuff that they wrote down over 100 years is still 100% relevant and also still helps identify what's going to roll down the hill next.
trying to understand why things are fucked has helped me immensely in coping with all the asshatery; it seems like you've already started your own work by posting here so maybe it'll help you too.
