Love that you don't get it. How lucky for you!
Work in a school where we have to place separate gangs on different halves of the year so that they don't meet each other.
Heartbreaking, really, at this time of the year when they know they're going to have 6 weeks without anything to do. They really are just kids and, although some of them (we have gang tattoos here and, what I thought were permanant gold teeth caps when I first arrived, but have since learnt you can remove them) look quite scary at first, they're individuals and their lives are pretty rubbish.
Basically, you're looking at kids whose parents either don't care for them or who can't (because there are too many kids/ mental health issues/ have to work), so they're out on the streets all day in really poor areas which are almost a ghetto. I live only a mile from school, but never see any of my students as they don't leave their poor area of inner London.
The main problem is that the kids' aspirations are so unbelievably low that they can't visualise anything other than what they know- and no, they don't tend to have access to a tv, so that's no help. Better than trying to provide them with an education the purpose of which they don't understand (what is university and why would they want to go?), would be to give them a week staying in a middle class house in London where they might have a garden and their own room.
