So many good things would happen if the coastal class occasionally remembered that the United States is a huge country with a vast interior. There are tons and tons of towns with affordable housing in Ohio, Kentucky, Michigan, Pennsylvania, and so on. The problem is that the incomes are lower, too – but that is fixable with remote work, companies being incentivized to hire locally, and so forth. There is really no reason why everyone needs to be centralized in 10 urban centers on the coasts.
