New York has gone from being an expensive place where one could probably manage to cut a few corners and get a livable flophouse for something slightly expensive to a place where real estate prices are just insane absolutely everywhere. Difficult to comprehend the degree and speed of population decline it experienced for awhile.
Hopefully excess demand for New York living leads to a bit of revitalization of some second tier cities which have the potential to be perfectly nice places if only a few more people moved in.
