There are a couple problems with the system

#1 Teachers need to be taught how to handly unruly kids. Most of the teachers are women and no offense to them but they are more used to being nurturing and supportive and hell most teachers are kids themselves when they start out, they need to have the cojones to COMMAND discipline rather than ask for it.

#2 Parents take shit too personal, they are told "Your child was acting up in class" and they hear "I picked out your kid for being bad because I don't like you"....hey parents, maybe your kids are fuck ups!!! And even if they aren't to insert discipline in your own home you should discipline them just based on someone else telling you. The reason the parenting system has fallen apart is because discipline takes time and effort and parents are too tired, self centered, or lack the intrest to follow through.

#3 Kids are babied too often and too long and it is the job of the child to test boundries and limitations, they don't always do it with malice but they ALWAYS need to be disciplined or else they will find loopholes and get their way, that's what they are programed to do from birth.
