Part five of Oprah’s discussion with Pulitzer Prize-winning writer Isabel Wilkerson and readers of the book, Caste: The Origins of our Discontents. The fifth episode in the eight-part series focuses on the fifth pillar of Caste, “Occupational Hierarchy.” Isabel explores how the subordinate caste are often relegated to menial forms of labor, which further cements their place in the bottom rung of society in the eyes of the dominant caste. We’ll hear from an executive from a major tech company, a manager who is in charge of recruiting new employees and a high school principal.
