The one I always use is "what socialization? The kind that occurs on the playground, or the kind that occurs on the schoolbus"? ....you can see the light click on if they are really interested and listening because..... you are right, it is 'Lord of the Flies" in both cases.
A family member actually thinks this type of socialization is good. Afterall, it's reality.
And that's the nature of the game in the public schools, but also in many high-end (i.e., expensive) private schools. And thus, curricula also become a mirror or reflection of the pop culture of the day, at the cost of academics.
