Excellent book by Richard Rothstein detailing the systematic, de jure segregation imposed on America by its institutions (not de facto but rather de jure, or enforced by law). He layers example after example on you, each page weighing the argument more and more, drumbeats that refuse to back away from this egregious history. Citing examples in San Francisco, Richmond, Chicago, Miami, Atlanta, etc. he builds his argument from decades of research.
Lots of other crazy bits are inside, like the 1917 campaign promoted by the Department of Labor in response to the terrifying 1917 Russian revolution: an “Own-Your-Own-Home” campaign where “We Own Our Own Home” buttons were handed out to schoolkids and pamphlets distributed saying it was a patriotic duty to stop renting.
