Much has been written about the history of racial segregation in America’s housing market — and for good reason — but less is known about the role of class-based segregation. Using early 20th century Los Angeles as a case study, Laura Redford discusses how developers used a combination of restrictive covenants, the judicial system, and advertising to build a divided city — one that not only separated white residents from Black residents and other people of color, but also maintained divisions by class: poor with poor, middle class with middle class, and rich with rich. Several idiosyncrasies led to Los Angeles pioneering this model, with many of its practices soon exported to other cities and towns across the nation. And while racial discrimination in the U.S. has been illegal (but not eliminated) for more than 50 years, class-based discrimination lives on more explicitly in present-day housing policies, with implications for both economic opportunity and racial segregation.
