Here is a noteworthy snippet from that article that you might find useful for future conversations about this:
In fact, a New York Times analysis of 2014 census figures shows that income alone cannot explain, nor would it likely end, the segregation that has defined American cities and suburbs for generations.
The choices that black families make today are inevitably constrained by a legacy of racism that prevented their ancestors from buying quality housing and then passing down wealth that might have allowed today’s generation to move into more stable communities. And even when black households try to cross color boundaries, they are not always met with open arms: Studies have shown that white people prefer to live in communities where there are fewer black people, regardless of their income.
The result: Nationally, black and white families of similar incomes still live in separate worlds.
