Hell's teeth!
Does no one see the repulsive creatures you get elsewhere?! Lol...
Having travelled extensively around the UK (currently living in Essex), i can categorically say (with only a mild touch of bias, of course) that 'your average chav-type' (as described above) is FAR more likely to come from ANY lower class, scummy area than specifically Essex! Perhaps if they congregate in such lower class areas where you live, you need to work out what to do with them... ship them back, perhaps...?
Of course we have our fair(?) share... but one really needs to develop a 'sense of humour' when dealing with these poor, working class, wannabes with their push-up bras, loud voices and 15 kids in a pram (where's the father?)... but i have a feeling that if you open your eyes and become slightly less 'short-sighted', you will find plenty of obnoxious, revloting types who actually originate from YOUR parts of the country... no, really.
:-o
