rainbow at the bottom of Page 7, you say that "If you live in a half million pound house then yes I do consider that wealthy, either you must have very high salaries to afford a mortgage of that size or you must have 100s of thousands in equity."
A fairly bog standard terraced house in London costs this much, and I can't imagine they are all owned by millionaires with ££££ of equity. More like struggling middle earners who have to work in London and have had to take out huge mortgages whether they can easily afford it or not.
Under your proposals, would these poor people have to educate their DC's privately? After all, as you say above, you "consider that wealthy".
Also, it is a sad, but true fact that most "poor" or "satisfactory" schools are in less wealthy areas, with higher rates of FSM, unemployment etc. The biggest impact on children's lives is their parents, and if they see their parents not working, having few aspirations etc, then lots, (not all by any means) of these children will have the same lower expectations of education and life than the children of "pushier" parents. And before anyone starts with me, I work in one of these schools in a designated disadvantaged area, so am not just spouting Tory bollocks.
Is is so wrong to want to want your DC to go to a good school? It didn't used to be a crime to want the best.
