I have interviewed many white people who have fond memories of their lives in the 1950s and early 1960s. The ones who never cross-examined those memories to get at the complexities were the ones most hostile to the civil rights and the women’s movements, which they saw as destroying the harmonious world they remembered.

But others could see that their own good experiences were in some ways dependent on unjust social arrangements, or on bad experiences for others. Some white people recognized that their happy memories of childhood included a black housekeeper who was always available to them because she couldn’t be available to her children.
