My pet, conspiracy?, theory is that the always online culture is perhaps to blame. We have a lot of anger, and depression out there and very little except for medication seems to be helping.
There have always been anger and depression in society of course but the rate of increase in extreme outcomes from those is definitely rising. Mass shooting, teen suicide, online or real world mobs are all up everywhere. Something seems anecdotally to have shifted. The pandemic was an external stressor of course but it exacerbated something that seemed to already be building.
I have resources and method to address this stuff for myself but I don't have any ideas to address it societally.
