The long and short of this matter is that poverty breeds ignorance and crime, and when you have families that have been in this way for generations what you have is an endless cycle of people being born into rough families with no prospects and they are so used to it that they just don't care any more. The parents have no standards themselves by which to set for their children, and the children see this and this makes them care even less. Ad infinitum.
People are having kids who should not be having kids, and unless you can find a way to stop this or miraculously solve unemployment etc then you have it for a looong while yet, and as the worlds popuklation booms this will be just the beginning.
The only solution would be a new FAR harsher poliving regime, or government-dictated birth control a-la-China.
Just my opinion as always.
