In her brilliant new book, Caste, Isabel Wilkerson speaks of racism in America as a caste system that is like the studs that form the frame of our house. We rarely see them or think of them, but they are there, holding the whole house up and if termites or mold get to them, the house will collapse. Racism establishes the social order so that even after the end of slavery, Jim Crow laws, lynching, segregated schools, restrictive real estate covenants, discrimination in hiring, and voter suppression kept much of our black population in the ranks of the “untouchables.” Ending racism will take a lot of work with many complicated steps but it must include closing the wealth gap, the employment gap, making education accessible, and dealing with the unequal distribution of healthcare, and correcting the current trends towards minority voter suppression.
