So far as I know, the system we have for looking after kids in our care (usually through no fault of their own) is to chuck them out at school-leaving age, usually with no qualifications, and then they're on their own. Because unlike other people's pseudo-independent kids, they've got no home or family to go back to. We've disowned them.
Then we wonder why so many end up in the criminal courts.
Well David Cameron doesn't wonder. He just thinks the lower classes are all criminals. Unlike any friends of his. But I digress.
