You are bringing up the argument for Welfare, Universal Healthcare, etc., that there is nothing that the schools can do. The problems that these kids are facing stems from the fact that they live in poverty. This leads to issues such as the one mentioned by the author. The only way to solve the problem would be to try to figure out a decent Social Benefits system for the poor, to where poor parents do not feel the need to resort to prostitution, drugs, drinking, etc.

Why do you think that the lack of a "decent Social Benefits system" is the reason why they do prostitution, drugs, drinking?
To put it another way, you seem to be assuming that someone drinks because they're poor. Could it be (for some/many) that they're poor because they drink?
