Edward Berenson describes the remarkable career of William Levitt, who did more than anyone else to create the modern suburb. In response to an unprecedented housing shortage as veterans returned home from World War II, his Levittown developments provided inexpensive mass-produced housing that was wildly popular--prospective buyers would camp out in line for two days for the chance to put down a deposit on a Levitt house. He was a celebrity, a life-changing hero to tens of thousands, and the pitchman of a renewed American Dream. But Levitt also shared Ford's dark side. He refused to allow Black people to buy or rent in his developments and doggedly defended this practice against legal challenges. Leading the way for other developers who emulated his actions, he helped ensure that suburbs nationwide remained white enclaves. These legacies are still with us. Levitt made a major contribution to the stubborn wealth disparity between white families and Black families, and his solution to the housing crisis of the 1940s--the detached house and surrounding yard--is a primary cause of the housing crisis today.
