There is a sub-culture in the US that scorns education and hard-work, doesn't frown on illegitimacy, doesn't hold fathers accountable for the offspring they produce and glorifies crime and violence. I think it's unfair to just associate this culture with blacks since plenty of white trash losers buy into it as well, however when you look at crime, education & illegitimacy statistics it's clear that African-Americans buy into it at a higher rate than anyone else.
No culture can thrive if its participants have a 70%+ illegitimacy rate. That's just a recipe for failure right there, like starting the 100 yard dash 50 yards behind the start line. Until blacks (and now more and more poor whites) return to the traditional family structure of two parents, they're going to continue to be mired in poverty as a group.
