Probably not directly, but it has that effect by proxy and the initial segregationist motivation is still in force. It's 2021 but the divides in wealth, living standards, outcomes, etc... still echo the racial divisions of the past. Hundreds of years of societal conditioning will take hundreds of years to fully revert.

The zoning laws also have a similar effect on those who are priced out by wealth & income, regardless of race, leading to rich enclaves & poor ghettos. These are harmful to society as a whole, which benefits from heterogeneity.

No, it's probably classism instead. Mandating that people rent or own a minimum amount of land means that you can keep poorer sorts out of the neighborhood, which also means their kids don't go to your schools.

It's gated communities, enforced by the government. And proponents want to act like it's morally acceptable because...democracy, or something? As if the fact that people democratically voted on something always means they're right.
