Has black American culture bottomed out at a historic nadir? (completely bankrupt)

After more than six decades of being black in America, I have to say that black people are actually at an all-time cultural low. While this degraded state has correlated with the decline of American culture, a rotting value system within the black culture is the ultimate catalyst. The national infection of the hip-hop sub-culture has spread from its origins in poor black neighborhoods to mainstream America.
