Doesn't have to be an age thing, but it often is an age thing. Because lots of us were carefree before dependents and a mortgage as well.
Unexpected or deliberate change was an opportunity, a challenge, a stimulant! Job hopping (or hopping around relationships) when young can be about exploring the world, finding yourself and your values and isn't inherently bad.
Then you discover what you are good at doing and that you like doing and dedicating time to (or perhaps another person with whom you want to spend all your time) and your priorities change.
Then you might have kids and the work becomes more about financial security for the family then about your personal growth. And so you aren't looking at layoffs and unexpected change as opportunity because you are happy with what you've got.
It just often is an age or 'stage of life' thing for many people.
