John Gatto:

This great school crisis is interlinked with a greater social crisis in the community. Children and old people are penned up and locked away from the business of the world to a degree without precedent. Nobody talks to them anymore, and without children and old people mixing in daily life, a community has no future and no past, only a continuous present. In fact, the name community hardly applies to the way we interact with each other at all. We live in networks, not communities, and everyone I know is lonely because of that.
