I do see it as an economic problem. Precarity is going to induce loneliness and tension. People are working more hours and there’s simply less ability to connect. There are fewer “third spaces” (places outside of work or home) these days, so people have reduced capacity to develop bonds with one another. All of that is going to generate mistrust and lack of friendship among people.
Political tensions are high too, for instance, I would refuse to live with someone who expresses casual transphobic because I wouldn’t trust them to be around me.
Furthermore this is a niche internet forum with a lot of nerds who have general social anxiety. Probably not a good cross section of a population.
