I grew up poor and have ADHD, so went to state comp. I will say that there were definitely unpleasant sides to it, but I feel like my compadriates and I have a much more rounded and grounded view of society and class than the friends I know that went to private schools. You simply can't expect someone who's never felt poverty, whether it's their own or the people they see day in day out, to be able to be able to truly understand it.

I can see how it would probably be a more difficult experience for introverts.

Funnily enough, I got bullied more by the rich kids - who knew how to push my buttons and wind me up to the point I'd lash out and get in trouble - than the poor ones.
