I think you need to reconcile reality with your view of reality. Just last week an African American professor was making the point that African Americans are increasingly integrating into historic "white" jobs, occupying positions of political power, and growing up in affluent communities. In other words, ever more African Americans are enjoying "the good life", so what about the other 25% that fit your description of their future.
Around 25% of African Americans appear to be locked into generational poverty and your description of that applies to many other groups including poor whites in rural areas, and Hispanics living in poor neighborhoods.
Perhaps focusing on why 75% of African Americans are not living in generational poverty and comparing them to the 25% that are, will unlock the causes of that generational poverty and what can be done to address it.
I do know several attributes of those stuck in generational poverty regardless of race have emerged from studies over the last 50 years and the results are pretty much the same no matter which racial group you study.
1) family history of not getting a high school degree and going on to college or vocational school.
2) family history of having children before age 21, even worse having children out of wedlock before age 21
3) family history of living in a place with minimum job opportunities and high violence/crime. These communities often have a "culture" regardless of race that imprisons by convincing them they have no chance, so why bother.
There is some casual and some correlation between these things, but rather than focus on skin color, it seems society should make sure a good education is available, and job opportunities exist for that education.
But you can't force people, and we need to make sure people understand they are responsible for taking advantage of educational and job opportunities and not making babies until after they complete their education, enter into stable relationships and have careers.
