Unfortunately that's a very difficult answer, one that a portion of the people in the black community have been trying to answer for decades now.
The simple answer is the black culture needs to be changed from the ground up. We have a culture that, even though we know it's wrong, idolizes things like gang life, violence and drugs (I'm speaking in general terms here). It's something that is honestly difficult to understand I think, unless you grew up that way. It's mindframe that's truly embedded in our culture.
As a people, we don't have the structural framework to support ourselves like just about every other race has to some extent.
And I realize I'm kind of all over the place with this post, but the issues are just too wide spread to try and summerize here.
It sucks.
