The feels correct to me.
I lived in New York City for 15 years. Until last year. I've thought about this theme all year. Decades of policy supporting foreign investment and developer speculation gutted the chance for even affluent upper middle class New Yorkers to afford housing and setup a home base, and so many left. The situation has been incomparably more challenging for low income residents.
I agree the urban collapse meme is much easier to spread than a thoughtful discussion about policy and priorities and how to balance the economic strength of a city's major players with the daily priorities of everyday citizens. I hope the New York remainders shift priorities and initiate a different kind of prosperous era than the one I got to enjoy.
