You clearly can change class (even if you don't want to and don't fill in the form at the post office :o )
scarydino did you mean me? I am thinking of certain specific individuals I knew slightly in my teens in a rural area of northern England - my parents are/ were upper middle class (by profession and outlook) and my sisters had horses and were on the fringes of the mixed farming and upper class types who had fox hunting and aspects of land management and possibly other stuff in common.
The people I'm thinking of own castles and manor houses by inheritance, own large amounts of land by inheritance, make their living owning and managing "sporting estates" or multiple farms run by tenant farmers, some are titled or (more often) related to somebody with a title which they don't stand to inherit, some lived full time in the countryside, many others moved between homes in London and the countryside - the younger men especially from that background were generally pretty unpleasant, in my direct experience. They really didn't believe rules on things like drink driving especially applied to them, and had a sneery and entitled attitude to women. They also believed that if the hunt ploughed through and trashed somebody's garden this was the equivalent of the garden being damaged in a storm and absolutely no responsibility of the hunt's, and had the same attitude to damage they did with their vehicles when they could get away with it...
Not everyone is like that I'm sure and of course it is wrong to generalise... Some of the much older (way post retirement age) people appeared not to be like that... Perhaps I just encountered a disproportionate sample of the upper class's arse contingent...
Every time somebody claims to be upper class and writes about breeding and pedigree it reminds me of them though... Some of the least pleasant people I have ever met...
