Thankfully we've moved on from the simple three tier system of class in the UK, based upon your inherited wealth and titles and having a posh voice. Any recognition of "class" today is a mix of education, attitude/behaviour and income/wealth. All of these things tend to be interdependen, but you can of course be rich and act without any class.

I'm thankful that we've moved on, as I've benefited a lot from free education and a reduction in snobbery. I was somebody that had a working class chip on my shoulder, but that quickly went away at university and at work.

I think as the current over 60s die off, we have another step change in the blurring/removal of class barriers. Older people in my experience do appear more deferrent to Lord and Lady whassname. Maybe that explains why they keep voting for Eton-educated PMs.
