I'm from "the global south" and things are going pretty well in my home country. Anecdotally, I notice a much stronger sense of optimism and less stress about basically everything.
Overall, I don't think civilization is collapsing. There's certainly big changes going on, but I think the sense of pessimism in english-speaking media is largely because "the west" or "the global north" reached an apex post-ww2/cold-war that wasn't going to last forever.
