The bad schools served the council estates and rough areas. My point was, that the biggest factor in how good a school is, is the students themselves. There can be an advantage in gathering the very best pupils together, but if you send different students to the school, it won’t be the same school anymore and they won’t get the same benefit. Maybe that’s the point, you want everyone to get the same mediocre education and not help kids reach their full potential? Except rich parents can opt their kids out of that, so it’s the poor but bright ones who suffer.
