Sorry, haven't read all thread, but this is Mumbles guide to class:
Upper Class - Royalty, other titled types, but not people who've been given a knighthood for doing something useful, eg Sir Richard Branson.
Middle Class - money irrelevant. Educated to degree level, reads the Times, Telegraph, Independent or Guardian depending on political leanings. Professional, charity giving, tax paying, Radio 4 listening, watches stuff like The Blair Years, West Wing, Spooks, anything with David Attenborough. Possibly privately educated/children at independent schools.
Working class - money irrelevant. Reads the Daily Mail/Express/Sun/Mirror depending on political leanings. Work in jobs like building, driving, cleaning, shop work. Radio 1 or 2 listening, watches Strictly Come Dancing, the X Factor, Big Brother, I'm a Celebrity. Possibly not quite so obsessed about education as middle classes.
There ya go.
