You can have offers "you can't refuse" even if you live in a major hub. But it's mostly the case that then it's a matter of you really wanting to do something on net as opposed to having to move to keep food on the table.
For some, +$20,000 to their current salary is an offer they can't refuse, for others, they would need to double their existing six figure salary to even consider moving to another hub.
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.
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 for a bit. But realistically not going to happen.
Once the basics and some future security are there, more money just means a bigger resource footprint. That's still nice to have, people certainly continue preferring wealth over poverty, but it would be crazy if trade-off thresholds between modesty and ambition didn't shift a little due to awareness of environmental impact.
Not 1.2 or 1.4 birds in the bush
