Anyone would move for a limited time period for a life changing amount of money like $20m/year.

But for realistic wages in my field, I doubt there is anywhere that would pay me enough to move. Short of moving into management (which I have little experience with) the most I could expect for making a move would be about an extra $40-60k/year moving to the Bay area which would basically cover the difference in cost of living and maybe a little extra pocket change.

That's not really worth it for me.

Yeah. When a lot of classmates were taking jobs in Manhattan I pretty much decided you couldn't pay me enough after having an internship there one summer. (This was back in the 80s to boot.)

But, of course, I didn't literally mean that. Offer me a few million a year guaranteed and I could put up with a lot for life-changing money. But realistically not going to happen.

If someone is offering $20m a year, I can safely assume the job is bogus and pass.

for $20M/year you are not really "moving". I are just getting another (very comfortable) place of residence, and you can travel as you see fit (incl. private jets).

Sure but I prefer to keep myself grounded in reality.

Then you wouldn't even move. Just rent some apartment for a year and then return home when you're done. That's more than enough to pay for a mortgage and rent.
