#19: The Darkest Rule Was Racial Exclusion
The ugliest restrictions were not about lawns at all. Racially restrictive covenants excluded Black families and other minorities from many American suburbs, including early Levittown agreements. The Supreme Court ruled such covenants judicially unenforceable in 1948, yet discriminatory sales practices and segregation persisted through the 1950s. These rules were not quirky suburban fussiness; they helped shape generations of housing inequality. Behind the cheerful ranch houses and manicured lawns sat a much darker system of exclusion.
