If that’s what the people who live in an area want, that’s a democratic outcome. Democratic outcomes are something that I’m inclined to support absent compelling evidence why they should be thrown out.
Was the majority of people that pushed for zoning laws that discriminated against minorities (it's mentioned in the videos if you don't know what I am talking about), or was it a systemic issue that needs to be corrected?
Do watch the videos, especially the "Strong Towns" series about the issue of how the rich suburbs are actually subsidized by poorer people living in bankrupt city centers. The only "straightforward" path for this to change is by getting younger people to participate a lot more on town hall meetings and to get their city councils on board with change. The status quo benefits and has no interest in doing that.
