there is a grain of truth in this. chav culture certainly existed and still exists in the south of england but they came in around 2000-2010 or so for much greater demonisation than their northern (scally) or scottish (ned) counterparts, likely due to UK media being concentrated in the south
the great chav danger was blown wildly out of proportion and i've no doubt the term expanded beyond the original sense of a sort of tracksuit/burberry clad antisocial petty criminal youth to include just about any working class kid in the minds of home counties handbag clutchers
so to say they never existed is false, and to say they never caused anyone any bother is false. but the middle class media confected version of them never existed in any great proportion either
