We are exactly like the US. Money is the only thing that matters in the UK as well.
But class is a necessary prop for at least one of our political parties. And, as the programme I heard yesterday said, as a whole, the better educated people are, the more leftwing their politics.
It is, therefore, inevitable that for the chattering classes that work in the media who, however well educated, are not renowmed for being deep thinkers, that lazy cliches like the 'class system' provide a ready made cliche responses that they can tote around in the media, underpinning their sense of superiority with a belief that they really 'care' for those less adept at climbing the greasy pole than them.
