I read the review. I was with you until I came to this one point in the review that seems to support homework for a specific population: affluent students. And the reason is that the parents make them do it and help them do it. In other words, homework for non-affluent students doesn't help because they aren't doing it and no one helps them do it. And Meier must buy into this because she suggests to Kohn not giving homework because the affluent will move even further ahead of those less affluent.
