Err, no. Infact a large majority of the 'underclass' in British society are white. I think the American term is trailer trash or white trash (sorry if that's offensive). As the previous poster said - the Asian community are actually the ones who push and push their children. Hard work isn't just encouraged - it's expected.
In the US, when children of color from disadvantaged backgrounds work hard at school, they are sometimes ostracized as trying to "act white." Is that a common occurence in the UK as well?
