I mean, what’s the point of living in a gated community if you need to drive to places filled with poors to buy shit, or have a beer, or hook up with someone in your tax bracket, or etc?
These are places where to sleep but not to live, and they put them really fucking away from basic needs. C'mon at least just put a fucking grocery store with overpriced tomatoes
usually a single developer owns all of the property and breaks it down into parcels to maximize profits. it doesn't want to sell a large chunk to a corporation because it maximizes profits by selling the quarter acres for tons of money. eventually someone with too much money will buy it regardless.
The land with the highest value is always the land furthest away from everything, unless you're inside an urban center.
