Has America ceased to be the land of opportunity? Many people here take it for granted that good neighborhoods—with good schools and good housing—are only accessible to the wealthy. But in America, this wasn’t always the case.

Though for most of world history, your prospects were tied to where you were born, Americans came up with a revolutionary idea: If you didn’t like your lot in life, you could find a better location and reinvent yourself there. Americans moved to new places with unprecedented frequency, and, for 200 years, that remarkable mobility was the linchpin of American economic and social opportunity.

Join us as Yoni Appelbaum, historian and journalist for The Atlantic, argues that this idea has been under attack since reformers first developed zoning laws to ghettoize Chinese Americans in 19th-century Modesto, California. The century of legal segregation that ensued—from the zoning laws enacted to force Jewish workers back into New York’s Lower East Side to the private-sector discrimination and racist public policy that trapped Black families in Flint, Michigan, to Jane Jacobs’ efforts to protect her vision of the West Village—has raised housing prices, deepened political divides, emboldened bigots, and trapped generations of people in poverty. Appelbaum says these problems have a common explanation: people can’t move as readily as they used to.

They are, in a word, stuck.

Applebaum will cut through more than a century of mythmaking, sharing the surprising story of the people and ideas that caused our economic and social sclerosis and laying out commonsense ways to get Americans moving again.
