Not that cost of housing should be the sole criteria when it comes to zoning policy, but it obviously is highly salient, particularly inasmuch as the backstop fix more and more tends to be rent control. Who do you rent to if a pad becomes vacant that is subject to below market rent control? Want to guess? A wall street investment banker or introverted CPA of course with no kids and no pets that reads the bible in a very quiet environment, and is not home very often. Of course, of course. That's the way it's done in Hoboken anyway. It is an upper middle class paradise of very polite young people mostly.
