> At the same time, many, many people love it.
Sure. That's what people tell themselves. Realistically, most people would prefer to live in a less dense area, but they can't do that because there are no jobs for them there.
> In NYC alone millions of people pay astronomical rents and mortgages for the privilege of living in tiny spaces in close quarters, no yards, etc.
Exactly. And it's getting _worse_ with every generation, right now NYC is at 530 square ft. per capita, down from 700 in 1980. It's even worse for Manhattan.
> It's not 'misery central', just something where you have a different preference.
Yes, it's misery central.

I analyzed a database of all real estate sales in the US for the last 25 years. There is plenty of other research that found similar results. The _best_ outcome was something like transient single-digit percentage decreases in rents near new construction.
I don't have the links on my phone, but you can google the "Supply Skepticism" paper from the Furman Center. It's a nice overview of the literature, and it's written from the viewpoint of pro-density (to prevent questions about bias).
