Pulitzer Prize-winning author Isabel Wilkerson says racism is an insufficient term for the systemic oppression of Black people in America. Instead, she prefers to refer to America as having a "caste" system.
Wilkerson describes caste an artificial hierarchy that helps determine standing and respect, assumptions of beauty and competence, and even who gets benefit of the doubt and access to resources.
"Caste focuses in on the infrastructure of our divisions and the rankings, whereas race is the metric that's used to determine one's place in that," she says.
