This is how segregation compromises the power of black community. It takes a societal ill -- say a lack of insurance -- and then concentrates it one community. Members of the whole community, uninsured and not, feel the effects of this to varying degrees, and a problem that is truly American somehow becomes "black." The black uninsured of Mississippi -- a majority of the uninsured of the state -- are not going to be evenly distributed among the various networks of the state. They are going to be concentrated in one particular network. What the state won't cover, private citizens must. Those citizen will tend to be black. The people who will have to drain their savings will be black. The people who will take out second mortgages will be black. The people who will pick up second jobs (if they can even get them) and miss parenting time will be black. You can multiply this out across social policy, and see how a wealth gap might be perpetuated.
