See How 'good White people' derail racial progress by John Blake of CNN. Excerpt:

"Political leaders can still prevent Black and brown people from moving into Whiter, more affluent communities by using exclusionary zoning laws that prevent the building of low-income housing or apartments, scholars and activists say.

This high degree of residential segregation is not restricted to red states. Some of the most racially segregated housing is in progressive cities like Chicago. 

 

This clash between a White homeowner's politics and the zoning laws that make their racial isolation possible can lead to some odd visuals, says Omar Wasow, an assistant professor of politics at Princeton University. Wasow says housing policy is "ground zero" for racial equality because it shapes access to good schools and jobs, as well as the ability to build wealth. 

 

"There are people in the town of Princeton who will have a Black Lives Matter sign on their front lawn and a sign saying 'We love our Muslim neighbors,' but oppose changing zoning policies that say you have to have an acre and a half per house," he says. 

 

"That means, 'We love our Muslim neighbors, as long as they're millionaires.'""
