Even if the world is a bit shit, there's still plenty of opportunities for love, family, friendship, art, music, sport, and plenty more. Maybe even working towards solving one of the big problems we face, whether that's through science/tech or politics/economics?
Maybe we need something to replace religion, without the dogma, oppression, and conflict. Something other than the online tribalism and activism seems to be filling that void for many...
If you want the world to change, you need to do that. You can't just wait for it to happen.
I don't know what the answers to the world's big problems are, but I'm pretty sure that smashing, burning, and pushing for violent revolution, insurrection, or civil war is not the answer.
(Obviously it's also great if a person can donate to charity or something of that nature. But obsessively following world events will make you miserable and solve nothing.)
