The expressions are usually upper class, middle class, lower class (working class). In days gone by the work status was often a good indicator - upper class people often had money "through the family". middle class people were managers and white collar workers, lower class were the blue-collar working class, and patterns of education could be followed through (public/private school, sixth form, comprehensive etc.). Nowadays the boundaries are much more blurred, a middle-class person is just as likely to be on the dole as anyone else. Katie Price is not high class, she's not an aristocrat - being famous doesn't mean you move up a class. There are many upper-class people that none of us have ever heard of, and many of them these days are as hard up as the rest of us. I worked with a woman who was a Lady, and apart from speaking better than me, she mucked in with the rest of us.
