I actually agree with MrLars... you are going to deal with those kids one way or another sooner or later, and educating them is the smarter way. How is the question.
If you think it would be better to have more uneducated, unemployable thugs standing on our street corners, fine. Better realize people will eat, and they need money to do that. They're gonna get that money somehow, whatever it takes, or die.
We may not like to have our tax dollars put into public schools, or even private schools for that matter, but we're better off doing so. In case people haven't noticed it isn't the 19th century anymore, and there aren't too many farms or factories left to absorb the excess of uneducated manpower available even today. Today's jobs require higher and higher levels of sophistication and education, and more, CONTINUED education.
What I guess I am saying is, you can pay for other peoples' kids to go to school for 12 years, or you can pay for welfare or prison for the same people for 50-60 years. Your call.
