Exactly. YMMV but that is 100% true in many urban areas. Too many people leads to less meaningful connections. I imagine much of this community lies in those urban hotspots.

it's going to continue. Low trust societies are a structural issue, and I see little initiative to fix it. People constantly need to move around due to rising costs of living, there's no commmunity hubs, third places, frequently meeting clubs, etc. to build such community. Work hours are creeping up while compensation and stability is going down. Where would you find the time to meet up?

It's all an economic issue at the end of the day. There's a part of the equation where we don't "need" to work with as many people anymore to get by. But for he most part, it's very similar to the walk-ability issue in the US. There won't be some mass change all at once, but people take cues and change heir habits around heir environment.

For my environment, I'm a night owl and everything in my town is closed by 8pm or so. I don't like the loud environments of bars. So there's nowhere for me to really go.
