Caste: The Origins of Our Discontents

IDEA 1
America has a caste system
Wilkerson argues that racism in the United States is best understood as a caste system: a rigid hierarchy that ranks people by birth. Like the beams of an old house, it is hidden but holds up the structure of society.
IDEA 2
Comparisons reveal patterns
Wilkerson compares American caste with India's caste system and Nazi Germany's racial hierarchy. She argues that all three share patterns of ranking and exclusion. She argues that seeing these shared patterns helps us understand how hierarchies in different places work.
IDEA 3
Caste rests on eight pillars
Wilkerson identifies eight pillars of caste, such as divine will, heritability, control of marriage and dehumanisation. These pillars keep caste systems in place. She uses these pillars as a way to compare very different societies.

IDEA 1
Millions left the South
Wilkerson tells the story of the Great Migration, when about six million Black Americans left the southern United States between 1915 and 1970. They moved north and west seeking freedom from segregation and violence.
IDEA 2
Jim Crow ruled the South
Wilkerson describes the Jim Crow system of segregation, which denied Black Americans equal rights and threatened them with violence. Daily life was shaped by fear and humiliation. Wilkerson shows that this pressure led millions of Black families to look for a new life elsewhere.
IDEA 3
Three lives tell the story
Wilkerson follows three people: Ida Mae Gladney, a sharecropper's wife; George Starling, a fruit picker; and Robert Foster, a doctor. Their journeys show different reasons for leaving. Wilkerson uses their stories to show that the Great Migration was made of many individual human choices.
