Mass exodus from Manhattan into the other boroughs. The biggest sacrifice you make in Manhattan is space, but you make it to be near your job.

Now that a lot of places are remote, the people who could afford a Manhattan apartment don't need it anymore and got tired of living in a shoebox.

You still get all the benefits of New York in the other boroughs, just in a 1 or 2 bedroom instead of a 5th floor studio walkup.
