Although it can be overstated, the real question (modulo the fact that, for geographic reasons, some cities and areas are better able to add housing stock than others) is why companies are willing to effectively channel large amounts of money to landlords and home sellers in certain areas of the country in order to be located there. I&#x27;m not sure the article makes an especially coherent argument on this particular point other than observing a trend toward more centralized industries.
