It's not just public school, but in general many forms of social capital[1] have taken a huge hit and will take a while to recover. Other kinds of social interaction and organization have taken a hit. Whether its local tech meetups, your school's PTA, concerts, farmers markets, etc, society has taken a hit. We see the impact in heightened crime, panhandling, and other signs of social distress. Even these small, seemingly trivial, kinds of organized social interactions created community and a chance for people to actually care about the state of organized society.
Pre pandemic, I feel we were in a positive cycle of renewed cities, increased social capital. Now it feels like we're in a negative cycle of people avoiding each other, leading to negative feedback loops and lack of social support.
