True, but I’d venture it’s even simpler than that - it’s easier socially to be critical of stuff than to be positive.

People complain about everything: their spouse, their children, their house, the small scratch on their fancy car, how many shows are on their streaming backlog, how complicated the travel was on their vacation, etc. These are all things that probably bring them lots of joy, but it’s so much easier to complain, so to someone (like OP in the image) hearing it, it sounds like the negatives outweigh the positives.
