At the same a lot of the kind of socialization you get forced to do at school is irrelevant in life. The minimum level of decency at an average workplace is much higher than at an average school and bullying much less common and you get to avoid most of the socially complicated situations school 'trains' you for.

Obviously there are a lot of benefits from socializing at school but there's really a lot you can do without. It would be much more beneficial to get kids to socialize in an environment where beating someone up actually ends up in the court.
