That is not what I read. I am hearing about plans being laid for migration out of the heavily taxed NY/NJ area for less costly areas of the nation, using the current situation to cover long-ranging relocation plans.
A significant mutual fund I get mailings from sent an email that says that their new investor services are relocating and giving information about the new offices in the south (I prefer not to say any more as it reveals investments). That's a major move.
That may be true for your investment firm but I don't think anyone seriously thinks Wall Street and the major finance institutions on the whole will be moving out of NYC. Covid lockdowns have given everyone too much time to imagine an apocalyptic future. Truth is, it has accelerated some shifts in the way we do things. Some will stick, some probably won't. Just because technology and necessity has shown everyone how to make things work remotely doesn't mean it's the best or most desirable way in every case.
Most people and companies that are located in New York are here because they want to be. Yes taxes are high but schools are rated among the highest in the nation and people understand that taxes actually pay for good things. Funny how the conservative media outlets that cry the loudest about taxes are all based in New York even though they could go anywhere else where taxes are low and the schools are rated 48th in the nation. I don't know anyone who wants to move from NYC to the south unless they come from there.
Plenty of people have left New York right now because they have to. People like Broadway actors, producers, crew, caterers - the number of people in that industry alone is huge. Virtually none of them have money coming in to pay the rent so some have left to go back to their hometowns and families for the rest of the year. But they'll be back. And the tourists will be back to see the shows, and so all the restaurants and supporting industries will be back. And the people who don't come back will be replaced by new people taking their places as business and the economy recovers. If you don't think that's true then you're not considering the inevitable rebound effect that will occur following Covid. None of us are fortune tellers but you should try consuming some positive media that predicts these things, not just the outlets that constantly fear monger.
