The U.S. government's active role in racial segregation quite apart from the Jim Crow South

Anyone interested in issues of racial inequality in these benighted states of America should read this; an excerpt:

[P]art of the book’s shock is just how explicit the government’s racial engineering often was. The demand for segregation was made plain in workaday documents like the Federal Housing Administration’s Underwriting Manual, which specified that loans should be made in neighborhoods that “continue to be occupied by the same social and racial classes” but not in those vulnerable to the influx of “inharmonious racial groups.” A New Deal agency, the Home Owners’ Loan Corporation, drew color-coded maps with neighborhoods occupied by whites shaded green and approved for loans and black areas marked red and denied credit—the original “redlining.” The FHA financed Levittown, the emblem of postwar suburbanization, on the condition that none of its 17,500 homes be sold to blacks. The policies on black and white were spelled out in black and white.
