One of the most pernicious drivers of inequality in the United States over the past half century has been mass incarceration. Moreover, the consequences of mass incarceration have been borne not just by those held in prisons, but by their families and communities as well.

First, Harvard sociologist Christopher Muller traces the historical roots of mass incarceration. He illuminates the close association between incarceration rates and the demand for labor, a relationship that has persisted from the 19th century American South down through the present day.

Then, Duke sociologist Hedy Lee discusses her work on the oft-overlooked effects of mass incarceration on the families of incarcerated people. From the mental toll on spouses and children, to the nickel-and-diming of prison commissaries, the conversation catalogs a wide array of unexpected costs brought on by mass imprisonment.
