Far too many black families do no have the luxury to choose a new value system. Extreme generational poverty is bad enough, but many are not allowed to even start on a path towards self improvement because 7.7% of adult black men are currently in prison. How, exactly, does "pro-family culture" improve social mobility for the 1-in-9 black children with a parent in prison.

Exactly - it wouldn't surprise me at all if the "benefits" attributed to marriage are actually a proxy for race.
