A lot of kids-at-risk are actually the children of baalei teshuva, and one reason for the pheonomenon is the fact that not enough support is given to bt’s after they become Frum. Obviously, there are many factors, but that is one of them. In any case, the baalei teshuva seminaries are aware of the problem and have started to work on it.
Your point is a valid and good one, and I did not mean that as a contradiction to anything you wrote.
I do disagree with your last sentence though. I think the school system is a very good one, and that they have put a lot of effort into these areas in the past generation. The school system today has changed a lot since I was a kid in precisely these ways.
Of course, there is always room for improvement, but it has to be remembered that it next to impossible to create a school system that will be the perfect system for each and every child, and that the administrators, principals and educators are putting tremendous effort to do what they can.
They can not be blamed for every problem. They may not even be able to solve the problem. And they work tremendously hard for the klal with little reimbursement and should be shown appreciation and not blame. (I’m not saying that you were trying to blame anyone. I don’t think that is how you meant your words – I just want to point out that one should not use this as an excuse for blame.)
