Isabel Wilkerson, author of bestselling book, Caste: The Origins of Our Discontents, presents a stunning explanation of a caste system that bypasses mere race and class as a rigid structure of human ranking that has been present since the start of this country. The McCourty Twins – star athletes, prolific philanthropists, and community activists – continue this thread, examining the impact of the caste system in health, particularly Sickle Cell Anemia, education and social justice. Together, tonight’s speakers will lead us in an exploration of philanthropy as a means for disrupting the American caste system.
