Yes, I understand that. I don't think sending them to an academic private school where they will mix with the daughters of Indian shopkeepers and pharmacists who are putting every penny into the school fees pot etc is any more elitist than you sending them to good local state schools in good areas.
I absolutely have never wanted to show them there is one true way to live though...all 5 children are very different. Some work harder than others, some have different interests than others. I've even maintain neutrality over whether the girls' sports, riding/school enthusiasms are any more meritorious than my son's computer games. I admire as much those that have drive as those that are kind. Sometimes one will say - I'm the "best child" and I'll set them straight on that.
I suppose your point narrows it down to the issue of whether we think mixing with different religions and races (in my children's schools - our borough is 18% hindu, loads of Jewish children as well and I think only 2 children including my daughter had 4 english born grandparents in her class at Habs and immigrants value private and learning education more than the locals) is better than them being in a state school with children of a different IQ and with disabilities.
So what mix do we all want? Do we think we want to ensure we have very very posh children in a class with those from the worst council estates - that is one mixing and you can achieve that by forcibly bussing chidlren around.
Another mix is the one I mentioned of entry by raw IQ old grammar school system, doesn't matter who or what your parents are or where they are from or their religion or race or whether their first language is English. in a sense we got that with our children, except you need also the parents to afford £10k in fees as we don't in most places have those grammar schools any more that are free.
Or other mixes - do we want to ensure we have classes with say fixed percentages reflecting the general population so x% black, x% with mental problems, x% with disabilities, x% with an IQ of 80 and x% with an IQ of 150 etc That's social engineering and I'm not sure it benefits the child.
I'm working today anyway so I'd better go.
