Ok sorry if it looked as though I was chickening out of replying.
I'm conscious this may seem a glib or cheap comparison, but in the 1980s, no-one who refused to buy Cape apples actually thought that Apartheid would end whether they did or not - they didn't buy Cape because they knew it was wrong, and didn't want to give tacit support to the regime. So, for me, there's an element of that attitude - even though the two things aren't directly comparable - in refusing to have anything to do with private education.
And what I think is that we have a country with a vast cohort of young people for who, inevitably and always, inequality will always be a reality. No-one is saying that if there weren't private schools, there would be no social class, no advantages or disadvantages, or that total equality would be achieved.
Now I could, can, and sometimes do be just anecdotal in the things I despise about a lot of private schools with which I come into contact, and doubtless many would find that every bit as offensive as I find the suggestion that my daughter at her state comp won't learn manners and morals, or doesn't get to do any 'extras', or that there aren't any/enough motivated parents at the school to make achievement a priority. But that wouldn't win anyone over - I'd probably just be accused of pretending to have a faith, or living in a massive house in a leafy area, and I wouldn't be so high-minded if I lived in the Bronx etc etc. In fact none of those things are true, but I have learnt there's little point arguing that as it just gets ignored.
But by segregating children according - essentially - to their wealth (and yes you can throw in cases of sacrifice and scholarship and so on, but it doesn't alter the fact that, basically, that's what the system does whilst there are private schools - then a situation is perpetuated which is little different from what Disraeli described in the 1840s:
"Two nations; between whom there is no intercourse and no sympathy; who are ignorant of each other?s habits, thoughts and feelings, as if they are dwellers in different zones or inhabitants of different planets; who are formed by a different breeding, are fed by different food, are ordered by different manners, and are not governed by the same laws."
