I think that becomes more common with income brackets that can start to feel like "enough".

If you've spent time struggling to make ends meet, even median income can feel like previously unimaginable wealth and security, and workplace satisfaction is rarely something that you had a great deal of choice around. If you've spent most of a decade making six figures with benefits, it's easier to decide an extra 10k or even 50k isn't worth the added stress.

Cost of living and personal situation (dual incomes, dependents) can shift that needle around quite a lot too.
