moomin And my children only considered those "elite"schools (it was their choice) because the 3 or 4 good comprehensives within a mile of my house were oversubscribed by 5 pupils for every place on first preference and my DDs didn't get in. They got in to the elite schools because of who they are as young people, their ability, personality, sense of humour, the qualities that we could only have nurtured, as you surely do if you enjoy and love your children.
There are some demented competitive parents who are as you describe at DDs school, and they tend to have insecure and competitive offspring, but they are the minority. None of the parents of my DDs friendship groups are like that, they are professionals and in other mainly middle class jobs, some SAHMs, several from other cultures making a life here. Down to earth families whose offspring are considering all sorts of futures, according to their talents, not parental pressure. My eldest DD is at a RG too studying Natural Sciences, and planning to go on doing that for the rest of her life, because she loves it, she will not, she has made quite clear, be paying for my care home 
Any differences between your life and ours are relative and in the context of the sorts of lives most people have a chance of, indistinguishable. But I am sure it is important to you to maintain illusions of superiority, and I won't let reality and a telegraph article designed to reinforce the stereotypes get in the way of that.
