The Engine That Drives Urbanism

Are we turning our cities into theme parks for the very rich?...We are pricing out the people who really make this place what it is and ought to be...A real city is filled with people of all incomes and interests, who spend their money in local stores and restaurants run by other local people, and their time out walking on the streets and playing in public parks, sitting in cafes, browsing and window-shopping, strolling and stopping -- after work, after school, after church or temple, before a movie, a play, a concert. That, more than mere commerce, is the time-tested engine that drives urbanism.
