I caught the last half of a somewhat quirky documentary on BBC Two the other night, called The New Middle Classes (it was part of the excellent Time Shift series). While it was talking about the "new middle classes" in the UK (which still has to be one of the most class-conscious nations in the world), one point they made rings true, I think, for 'middle class' people everywhere: the sense of guilt alleviation and self-satisfaction that is brought along by doing the 'right things'.
