A 'Forgotten History' Of How The U.S. Government Segregated America, Terry Gross, NPR, May 3, 2017, available here

In 1933, faced with a housing shortage, the federal government began a program explicitly designed to increase — and segregate — America's housing stock. Author Richard Rothstein says the housing programs begun under the New Deal were tantamount to a "state-sponsored system of segregation."

Rothstein says these decades-old housing policies have had a lasting effect on American society. "The segregation of our metropolitan areas today leads ... to stagnant inequality, because families are much less able to be upwardly mobile when they're living in segregated neighborhoods where opportunity is absent," he says. "If we want greater equality in this society, if we want a lowering of the hostility between police and young African-American men, we need to take steps to desegregate."
