More on the policies you mentioned that perpetuated housing segregation. From Quinetta Miller’s review of The Color of Law: A Forgotten History of How Our Government Segregated America by Richard Rothstein.

“…in the 1920s the federal government administered Federal Housing Authority-backed loans to developers building segregated public housing. In the 1940s and 1950s, the federal government authorized exclusionary zoning laws for newly developed suburbs.”

“Present-day disparities in wealth and income between African-American and white households also can also be attributed to these unconstitutional federal housing policies. Many African-American families could afford homes in the suburban subdivisions that were developed post-World War II, but they were prevented from doing so because of their race. I think that bears repeating — they had the money, but they weren’t allowed to buy homes and build wealth because of their skin color. Instead, they were forced to live in apartments or accept contract arrangements with inflated monthly payments. Meanwhile, white families have accumulated wealth through generations of homeownership and home equity.”
