Well, if the fathers are absent, (short of getting out) it's up to the mothers to protect/shield the kids from bad influences - join the nearest church (even if you aren't a believer) - get the kids involved in church activities, stress the value of education and have high expectations (hard work and best effort). Ben Carson grew up in Detroit and his mother couldn't read but she had high expectations and he got out - I know that was an unusual example but better than just lying back and having this hopeless acceptance.
Maybe other famous black people (President, basketball players, rappers, etc) on a rotation could go into these communities and give motivational speeches on education and how it's possible to get out/make a success of life, etc. And yes, if vouchers were available for computers, a HS degree can be totally gotten online - not going to drug and gang infested schools. Any extra money these inner cities get should go toward computers for young kids - the internet would open up a whole new world to them and better to be on the computer (even playing games but better reading) than on the streets.
Part of the problem of receiving help is the safety issue. When I first joined the adult literacy program at the library, they sent me into this really rough neighborhood. I told them I would continue in the program but only from my local branch (the person has to drive to me). There are people willing to help but not at the expense of their own safety and Th'Pusher - I already know your opinion on my fear level.
