Regarding areas of employment in a 'working class vs middle-class' discussion, I think it's a bit misleading in that given the disappearance of the industries traditionally associated with 'working classes'. There's no real manufacturing base any more and many 'working class' people are now employed in areas that would have once been seen as very 'middle-class'. Think how many people are now employed in some kind of office environment or other.

The changes to technology and economics and the knock-on effects to society generally has blurred some of the previous distinctions between 'working-class' and 'middle-class'.

That's not to say all the distinctions are becoming blurred though - I read a few things last year that suggested social mobility was becoming harder rather than easier and that relative levels of poverty were also increasing rapidly.

Maybe in ten or twenty years we can expect to hear a januty 'The Lincolnshire PVC window-fitter' or maybe Bert Jansch could do a haunting refrain about shopping 'malls' called 'Bluewater Side'.
