It is a complex debate, I agree - definitely one the nation needs to have, but from an open and non-defensive point of view. We need to be open-minded enough to look at facts & figures in depth and listen to people's experiences without saying "Ah yes, but..." (y)
There are also obvious problems like social deprivation which, by its very nature, tends to be concentrated around 'hotspots', for want of a better word, and this desperately needs addressing, because it affects everything - results at school, young people's ambitions, their behaviour - everything.
The deliberate government policy of forcing financially struggling people to struggle even more is not only mean spirited, but counter-productive too. In a society in which people from BAME groups is already unfairly and illegally discriminated against, then being poorer than everyone else as well is bound to create tensions and resentment. If you don't consider yourself as being part of society, then sooner or later you are likely to choose to live outside its laws and conventions.
I think all the above is fairly obvious stuff really but we need to look together as a nation at how we can do better. Sadly, on some/most days I don't think we will or can do it. Everything would need to change, including government and the poisonous behaviour of our print media, whose awfulness filters into how so many people view the world around them. I don't see either of those things happening anytime soon, but I live in hope.
