The New York equivalent of wealth porn is real-estate porn, because it's much harder to get into some buildings than to get rich: You can have all the money in the world and some co-op boards will still reject you (as they did Madonna and maybe also Henry Kissinger at some point) because they see you as "the wrong sort."

But you have a point (a couple in this gets to live for free in a four-story mansion). It's just hard to know what the author intended when she's called the novel a "comedy."
