>Part of the problem is, as you mention, the schools. But the other, much harder part of the problem, is the homes. If your parents aren’t engaged in parenting and you come from poverty, you are at a disadvantage that in no way can be fixed by the time you spend at your school each day. You’re treading water at best.

A fair point. Although I came to the conclusion when I was in school that while the impact of your home life is important, providing a positive initial experience with school and having high expectations for scholastic performance can do a lot to improve educational outcomes. Perhaps even enough impact to counteract the lack of parental involvement/motivation for education for some.
