Is it that they were finding themselves and then, as they get older, there's less undiscovered territory, or is it that they get established and moving is hard?
Bothish. They're hard to separate out. There's always new territory but with fixed lifespans we often give ourselves fixed discovery periods. We discover as much as we think we need to settle in the best place - all aforementioned things considered.
I wonder how many people would keep the hyper-aggressive moving, for fiat-related reasons, if they weren't getting tethered (no pun intended) by family constraints, etc?
Probably a lot. We have less family formation so we can already see this happening, eg rise of gig work, traveling for the photoshoot, side hustles on side hustles, etc.
I also wonder how much of this will change as a result of the full-remote changeover.
Employees<>employers are more liquid and fungible than ever before. It triggers a nostalgia in me for time periods I didn't even live in. The monetary stuff should at least allow older folks to leave the goblin workforce sooner and settle into being a proper gnome.
