I think you're giving them a little too much credit. Plenty of disruptive kids have a perfectly fine home life, have an iPhone, get expensive toys or technology bought for them. A lot of them are just jerks who were never punished by their parents, received few punishments from teachers and staff who had little power, and enjoy being disruptive or bullying others, and don't give a shit if they flunk all their tests o…
