Pretty much what carnell said. I went to a state school with limited streaming, ie in the sciences and languages, but not the arts and humanities. It wasn't a high performing school, but by and large as alumni we run the gamut of possibilities from dead, through prison, to doing alright to doing pretty well, whatever that means. The brighter kids from good backgrounds seem to all be ok regardless of hanging around with the oiks and certainly some of those from the estates have done really pretty well too. I liked that my (experimental as huguenot liked to call it) school did this, it offered intangible benefits that streaming and grammar/private models simply can't offer. A different experience, growing up with a much wider range of friends. I was probably the poster child for the theory, i was always sitting with the oiks, helping them if they found it difficult, encouraging them to want greater things than their parents had mapped out for them, and i in turn got to be cooler than my spoddy middle class background suggested, i got to hang around with nutters and girls out of my league and smoke drugs far too young....I'm not selling this am i. I get that in this day and age as bob suggests, money makes things self-selecting, but then the school was not great in terms of results or oxbridge candidates, but it had a clear ethos about wanting to create rounded human beings rather than churn numbers through tick boxes(not that you can churn wth a tick box). Yeah no idea what my point was any more....i'll get my coat.
