Sara Lawrence-Lightfoot

Sociologist Sara Lawrence-Lightfoot has written a new book about the Black middle class, called "I've Known Rivers: Lives of Loss and Liberation." She follows the lives of six middle-aged, African American people on the "necessary losses" they paid for their privilege. Her book was written, in part, as a response to the 1957 book "Black Bourgeoisie," by the black sociologist Franklin Frazier.
