"Our school crisis is a reflection of this greater social crisis. We seem to have lost our identity. Children and old people are penned up and locked away from the business of the world to an unprecedented degree; nobody talks to them anymore. Without children and old people mixing in daily life, a community has no future and no past, only a continuous present. In fact, the term “community” hardly applies to the way we interact with each other. We live in networks, not communities, and everyone I know is lonely because of that. In some strange way, school is a major actor in this tragedy, just as it is a major actor in the widening gulfs among social classes. Using school as a sorting mechanism, we appear to be on the way to creating a caste system, complete with untouchables who wander through subway trains begging and sleep on the streets."
