That is the crux of the problem
however
I have read that 80% of black kids have only a mom at home
or grandmother
not even a fighting chance with those situations
Well lax I would say yeah it's gonna be harder for them and in the neighborhoods they live in makes it even harder. But a good, strong leader of Mother can do it if she is not lazy and has her shit relatively together. My dad died when I was young (6) my Mom stepped up to the plate, got herself educated (College degree from St. Xavier's) was able to buy us a new house in a decent neighborhood and she stayed strict with us. She did not let us just do what ever we wanted, she made sure we went in the right direction. Even though I fought it and made life her hell at times. Was it the best circumstances? No, but it turned out OK in the end.
I have seen documentaries on the ghettos and sometimes you will see these single parent kids with good strong mothers and the kids are good, smart, determined kids who are not in the gangs and they are getting ready for college you know they will make it just hearing them talk. Same hood , same # of parents situation just one parent is good and does the right things the other not. So yeah its all about the parents or in many cases just the Parent.
