Sure it’s concerning seeing the movement. But, couple of things that I think about...
1) Assistant/staffer life is a tough life. It’s very common to move consistently to elevate your status, especially early on.
2) Riding the struggle bus for a couple of years, job security means something.
3) Upstate NY Winter is a hard life with weather & such, some people just don’t like it when they get here.
4) The pandemic has affected a great many things, and where you want to live may be one of them. NYS has not made it the easiest place to navigate.
5) Taxes suck on big money. That’s real.
Probably a combination of a number of these things and others.
There will be plenty of capable people to fill the roles.
