I'm not going to make any comment on 'chavs' or their equivalent. People who exhibit the tendencies which get them called 'chavs' today have been with us in one form or another since time immemorial.

I think one of the most 'knowing views of, and comments on the life and times of the type is to be found in the lyrics of Ian Dury (no chav himself, by the way, in spite of common opinion to the popular). "Billericay Dickie" and "Blockheads" are witty and actually quite affectionate takes on this aspect of society. Worth a listen...
