Ok, Time for me to Rant and Rave a bit about previous comments.
First, a child or children are at school approx 7 hrs a day, and if I remember correctly there are 24 hrs in a day. This leaves 17 hours for sleep, play, chores, school work, eating, and Parental Time. Notice the Capital Letters on PARENTAL TIME. The main issue is the parents teaching right from wrong. This is not an issue of coming from a school system, the school system teaches the same 2+2=4 to all, no matter where you are from. The bottom line is Parents. You can teach your child right from wrong, you can help them get better grades, you have the obligation to teach them, to pass on the knowledge you have attained. This is called parental evolution and if you don't teach them the things you have learned, and the difference from right and wrong, they may end up holding a pizza guy up for 30 bucks and wind up dead.
So lets not start in on the education system because your childs education starts at home. If they fail, then you failed to make them a better part of the world.
