I agree with you hub but again, where is this notion that in order to get a good education you need to be either exceptional, or affluent?
As I said pages back, no-one sets out to give schools in deprived areas the worst teachers, the worst facilities, the worst management, the worst discipline. Where does this idea come from? It's a lazy assumption and there is too much emphasis on blame.
Poor children do not thrive in education because someone else is doing.
What, exactly?
Do schools in deprived areas not have streaming, so they bright hard-working children can learn without disruption? It's the non-bright hard-working ones who suffer -they often end up in the classes with the badly behaved kids.
Schools that go into special measures or have reputions for being consistently 'bad' are very very rarely found to be in areas where there are few deprivation issues. It is unrealistic to always blame the schools.
If anything it is because too many kids who have grown up in an environment with low parental expectation and low aspiration are lumped together geographically, and so the benchmark would appear to be set very low in some schools. But unless all schools were forcibly mixed up and children were bussed all over town in a huge feat of social engineering that can never change.
And that won't happen. Not only is it impractical and prohibitively expensive, but the parents who are denied a place at their own very good catchment school would refuse to pay travel expenses to take their child 5 or 10 miles away each day, when there is a very good school on the doorstep - why should they? And the state can't pay the travel for every pupil, though of course they would offer to pay if for low-income parents.
And many would pull their children out if they didn't get their school of choice or didn't fancy the risking the experiment, and either home ed, go private, or set up co-op schools. No-one wants to compromise their own child's chances to even up the score.
That may seem selfish, but each parent's default setting is to want to do the best they can for their child, and let others take care of their own.
