In England, money doesn't raise your class status. That is very much an American thing. You can be poor and upper class and rich and lower class.
Proper Classes (should anyone be intrested)
Bear in mind that this is only a ROUGH guide, not a definitive one. For example, taste in fashion and leisure pursuits come into it quite a lot but are not mentioned. (You'll notice how money is absent).
Under Class: Unemployed, benefit scrounging tower block etc.
Traditional Working Class: Low or no education, factory worker, manual labour etc.
Skilled Working Class: Builder, Plumber, white van man etc
Lower Middle Class: Educated but not to university standard, speak in regional accents, live in average suburb, do a semi-skilled job.
Middle-Middle Class: Possibly university educated, but probably not from an educated background, own their own small companies or are lower-middle management in a large company. Live in decent suburbs.
Upper-Middle Class: Parents probably educated to a good standard, probably attended a good grammar or private school (in the English sense), not necessarily of upper-middle origins. Might speak in a mixture of accents. Successful business owners, higher level management etc.
^^^These two classes get blurred job wise VVVV
Lower-Upper Class: Come from an educated background, probably educated to University level if not higher, probably attended public school (in the English sense public school), traditionally speak in received pronunciation, Doctor, Lawyer, Army Officer, Academics etc
Upper-Class: Not necessarily titled but probably. Attended a good public school (English Definition), as did rest of the family. May not own an estate but probably have at one point in their family's past. Everything from Landowners, to MP's, to Army, to Priests.
Nouve Riche is in a class of its own slighty off to the side, next to middle class.
