content: Huh? Most public schools have a playground and recess, where children can "freely associate," not to mention that children "freely associate" in private, after school (I.e., neighborhood kids playing together). Not to mention, Private School is also an option for those who can afford it, and for those with poor public schooling. Homeschooling is an option for those with the time and propensity to do that, but it's not feasible or desirable for everyone.
