An excerpt from the article:

If the petit-bourgeois American suburbs embody a sexist hierarchy, they exist in order to enforce a racist one. In the mid-20th century, white northern and western urbanites faced a choice: Stay in the cities where Jim Crow was driving a “Great Migration” of millions of black people, or flee to the new suburban residential developments, complete with racist exclusionary charters. The Federal Housing Administration made the choice easy: Its policy redlined neighborhoods where black people were settling as having low “residential security,” thus making financial services inaccessible. In white-only suburban communities, however, the FHA was pleased to guarantee home mortgages. “There goes the neighborhood,” said millions, and fled.

I’ve said it before and I’ll say it again: pretty much every problem we have in the US is, at its heart, a consequence of bad zoning policy.
