— Population growth is fastest in cheap land areas.The fourth fact really is important. If you want to tell an analytically correct story about the future of America, the story is that more and more people will be living in suburbs of large and medium-sized cities in Texas. But to focus on the fourth fact without noting the other three is missing the boat. It's like saying nobody wants to buy a Lexus, or gorgeous Caribbean beach resorts in February suck. Luxury goods aren't unpopular, they're just expensive. San Francisco is expensive. Manhattan is expensive. Logan Circle, where I live, is expensive. But the difference is that policymakers actually have the ability to make it possible for many more people to live in these expensive places, they simply choose not to do so.
