I lived in Manhattan for 10 years from late 90s into the late 2000s, live in NJ now. A major trend I have seen is NYC skewing more and more towards the rich/ultra rich and ignoring the rich and middle class. We recently visited NYC for the first time in a couple of years, and it seemed like everything was transformed into Gucci and YSL and Bulgari etc etc.
I don’t know how this is sustainable given that Manhattan is an island.
