But the things that really stood out most in my mind from the housing forum were not part of any PowerPoint. They were a couple of offhand comments by a consultant, Rick Jacobus: • First, he mentioned that data shows that mixed-income neighborhoods are good for everyone—both the higher- and lower-income people who live in them. Which is an important reminder for people who keep arguing that the only solution is to just have developers keep building whatever and wherever they want, without much restriction, and let the market take care of it—meaning let the centrally located, amenity-filled neighborhoods with expensive land prices house the rich, while the poor and middle-class are pushed out into outlying, less-accessible, transit-starved neighborhoods where land prices are cheap.
