> If someone built a gigantic apartment complex next to your house it would mean that the demand for housing in your neighborhood was massive

or it could mean a developer was very stupid to overbuild somewhere, or more likely it's a shell building used as a money laundering scheme for organized crime (See https://www.theguardian.com/us-news/2017/nov/17/trump-ocean-... for one such building built by Trump; such buildings are also often structurally unsafe such as the building in Florida that collapsed which was also started as a money laundering front). I'm not down with this "the free market will make sure everything is OK" idea.
