I am seeing reports that everyone that had any ability to leave NYC has done so. It is basically a ghost town.
The real question is how many middle class and upper class NYC residents will refuse to return to the Big Apple.
Covid-19 has shown people that they can work from home, meet by video conference, and illustrated the potential risks/downsides of living in a big city.
It will be interesting to see what the long-term impact will be.
