" A city is successful not when it’s rich but when its people are happy. Creating bikeability and walkability shows respect for human dignity. We’re telling people, ‘You are important—not because you’re rich, but because you are human.’ If people are treated as special, as sacred, even, they behave that way. We need to walk just as birds need to fly. Creating public spaces is one way to lead us to a society that is not only more equal but also much happier. "
