Btw, my own DC goes to a private London day school for secondary. We pay the full fees and all the trimmings. Meeting the other families and seeing who is there is an eye opener. Aside from a couple of very poor token busars, there are a lot of people cocooned by wealth, as opposed to just high incomes. The DC there are lovely, the families are warm, kind and delightful. Typical, average, down to Earth it is not, however.
Meanwhile, I still live in the community that I have for the last 17 years. I am still involved in life in our "village." DC that I have known since they were mere dots, are at the local, leafy comp. Many are bright, sparky things with bags of potential. My own DC is pulling away from them at an alarming pace. After just a few years, I don't see how the gap will ever be closed. My own DC is simply being taught more and more rapidly.
It seems to me, that our local comp has had over thirty years, with no grammar school to compete with, to get its act together and deliver for the more able end. It's never succeeded. I support my neighbours and friends in wanting something better for their DC and what's more I think they deserve it.
