The "ghetto" culture will never change because they by-and-large believe themselves to be victims of a system gamed against them, and their only hope for change must come from some external force (the government, Al Sharpton, etc.). Their victim mentality is reflected not only in the poor quality of their schools, but also in the poor quality of the neighborhoods, their homes, and their parenting.
I was raised poor relative to many of the people around me, but my parents told me I could accomplish anything I put my mind to, they continually improved the living environment for my siblings and I, and they never once implied that our problems were anyone's doing other than our own. That is what creates success; not white skin.
The government can't stop those with the mind to provide a better education to their children from finding a way. Close the inner-city schools and force so-called "desegregation" on charter schools, and while the inner-city kids fuck up new schools, those with the means will move on. And then repeat. Always repeat.
