"ned" or "chav" is just a convenient way for the comfortable classes to write off a complex social issue. Do you laugh at homeless people, the disabled, or ethnic minorities? I'm sure at most you just express some kind of politically-correct fake pity towards them, much the same way celebrities announce their donations to charity in order to make themselves look good. Delinquency, poverty, poor education, and all the consequences of these problems are not something to be ridiculed, if you guys actually gave a fuck about anything other than your own material interests, maybe you would realise that social responsibility extends beyond the payment of taxes and sticking 10p in a charity box.
