Let me be clear. I am not stating a causal link between black political power and the living conditions and welfare of many of its citizens in these cities. It's simply an argument that the expectation that political power will translate into economic power for the ordinary citizen is apt to be disappointing. But there're some political steps that black politicians can take that can create an environment for economic power.
Crime exacts a huge cost on people least able to bear it. High crime makes everything worth less, whether it's houses or businesses. Among other things, it means fewer neighborhood consumer choices and neighborhood employment.
Black politicians should develop a ruthless zero tolerance anti-crime policy. Rotten education in these cities where blacks hold dominant political power needs to be addressed, but that's more difficult. Black politicians are beholden to and serve the interests of the powerful teachers' unions, and not the voters who elect them to office. Otherwise, they wouldn't begin to tolerate the near systematic destruction of learning opportunities for generations of black children. A solution is to break the education monopoly through educational vouchers.
