If government had declined to build racially separate public housing in cities where segregation hadn’t previously taken root, and instead had scattered integrated developments throughout the community, those cities might have developed in a less racially toxic fashion, with fewer desperate ghettos and more diverse suburbs. If the federal government had not urged suburbs to adopt exclusionary zoning laws, white flight would have been minimized because there would have been fewer racially exclusive suburbs to which frightened homeowners could flee.
