Yes, the UK middle class is over-represented at Oxbridge, but the definition is so narrow that they are outnumbered by the lower classes - state school kids and other riff-raff constitute two-thirds of Oxbridge classes, especially outside the upper-class signal subjects like Classics.
Well that's hardly the middle is it.
If the former, it might be worth remembering that ARM, which many consider the be the next big leap in computing (there was a thread saying it just yesterday) is an English company. Of course I could give many more examples, the technology you're using to post this comment for one, but I think I've made my point.
If the latter, I imagine thats too generic a group to say
I studied abroad for a semester in England, and in one of the classes I took there the (Australian) professor asked us what socioeconomic class we thought we belonged to. It was a good university, but most of the British kids answered "working class." When he asked "Why?" they answered, "Because our parents work."
That always stuck with me. In England, the aristocracy is alive and well. They don't have to work, and they don't pretend to. They do live comfortably, but they're highly educated and reasonably well adjusted. They don't have to partake in the charade that they pulled themselves up by their own bootstraps, and they generally don't blow their family's fortune over a debauched decade in Vegas like their American counterparts either.
