So the parents bear no responsibility?

???

What kind of education will a child with the best parents get from urban schools such as this?

While your point is true, it's irrelevant to the issue being discussed.

Your question is a non sequitor. A teachers job is to teach the curriculum, not to be a referee, lion tamer, etc.... How much more can a teacher do if the children behave a civilized human beings as oppoesed to these delinquents

While your point is true, it's irrelevant to the issue being discussed.I disagree my point is the single most relevant issue. Children in other countries learn more and better simply because they behave better. The crap that happens here is not tolerated.
