Historically, residential segregation split communities between the black inner city and white suburbs. This phenomenon is due to white flight where whites actively leave neighborhoods often because of a black presence. There are more than just geographical consequences to this, as the money leaves and poverty grows, crime rates jump and businesses leave and follow the money. This creates a job shortage in segregated neighborhoods and perpetuates the economic inequality in the inner city. With the wealth and businesses gone from inner city areas, the tax base decreases, which hurts funding for education. Consequently, those that can afford to leave the area for better schools leave decreasing the tax base for educational funding even more. Any business that is left or would consider opening doesn't want to invest in a place nobody has any money but has a lot of crime, meaning the only things that are left in these communities are poor black people with little opportunity for employment or education."
