Jane Jacobs was a needed antidote to the ethos of Robert Moses, which held that the long term regional interest always trumped the short term local interest.
Unfortunately, New York City took an overdose of the antidote, from which it has only now begun to recover. 30 years on, JJ has been used to justify NIMBY and BANANAs policies that benefit the tastes of the incumbent affluent at the expense of everyone else.
Is balance possible, or will NYC either go overboard in the other direction or retreat into stagnation?
