I hear your side from my daughter who teaches high school students. As good a teacher as I believe she is, it's very difficult, to say the least, to teach 16 and 17 year olds high school subjects when they can barely read.
A couple of years ago she had 3 pregnant 16 year olds in one class, one of whom was pregnant with her second child. It's clear to me that such kids aren't interested in learning, why bother to go?
Such children are destined, by their own choices and lack of parental guidance, to be a burden on society whether they attend high school or not.
The public school system may have played a part in this failure but the primary responsibility for it shoud be placed firmly on the parents, or lack thereof.
