The same community where I grew up biking, walking, and wandering around as a child now has police who say that they must respond if an adult calls in about unsupervised children anywhere in town.
A combination of rising costs, privatization, social media, and smart phones has made it so children can't spend time together without adults monitoring them. They literally are not engaging with each other in physical space the way that many of us engaged with each other as children up until the 2000s. We can see and feel that things are different as adults, but for children the real impact is socially and emotionally stunting. Children no longer have any low-stakes space where they can experiment and learn. And when we destroy the physical, in-person community where children can find support and comfort, should we be surprised when they latch onto the loudest people on the internet?
