The Coin by Yasmin Zaher

 There are always wealthy individuals within marginalized cultures—often, they spend their lives trying to decipher why fate made them rich while leaving everyone else struggling. Not as a life mission but more like an intellectual parlor game. This type of discussion occurs right before your servers bring you breakfast. The Coin forces this question on its protagonist: someone who could live anywhere yet decides to live in a 'grimy' New York City. The novel takes place in my neighborhood. Then it takes place in Paris. Another rough city blanketed by its architecture and haute couture. Regal yet deeply manic. She opposes the system while remaining comfortably ensconced in its luxury. Without giving too much away, she works in a school teaching middle schoolers, has a situationship with a wealthy Russian who lives in the "Evil Building" on Flatbush and goes into a Birkin selling scheme with an unhoused man.

Surprisingly, there’s little mention of social media, though perhaps the "Out of Site 1%" she belongs to would find such an obsession a little too gauche. It's a worthwhile read for those curious about this lifestyle, but you might be better off reading something else if you're short on time.
