Lyndon Johnson's Great Society has destroyed the black family - young males turned into feral criminals and imprisoned, young femailes pregnant before 16, children raised by single grandmothers.
It's taken almost 50 years - two to three generations - for these policies to destroy. It will take at least that long for the damage control.
And the damage control is going to have to come from the leadership within the black community - clergy and reasonable politicians (who are admittedly few and far between). It can't be imposed from outside the community.
