"We have chosen, over and over, to limit and constrain development. And that has, everywhere, the predictable effect of driving up housing costs. If we built enough housing, we would still need subsidized housing for many people, but market prices would be low enough that most people could afford them. But we’ve chosen not to. And the reason we give for that choice, more than any other, is that we are trying to preserve or improve the character of our communities."
