Last night I watched Citizen Jane, a recent biopic about Jane Jacobs and her long fight against Robert Moses’s plans for New York. Of course, Jacobs was largely correct: Moses’s grand utopian schemes wrecked the ecologies of street and community and eventually produced neighbourhoods worse than the ones they replaced, whilst failing to solve even the problems, like traffic congestion, they seemed best suited to. But being already familiar with the substance of the dispute, and with Jacobs’s great work, *The Death and Life of Great American Cities*, what struck me most forcefully was the rhetoric. On the one hand, there were the self-proclaimed “experts”, on the other, ordinary people with their lived experience, sceptical about whether the “experts” had their best interests at heart (or if they did, whether they shared the same conception of their interests). A great irony of the Jacobs case is that though she was right about Moses and his plans, the net result of her activism has not been, in the end, to preserve those neighbourhoods for the kinds of people who lived there then, but rather to give them an afterlife to be enjoyed by the people who can now afford to live in them.
