In my experience working at a 4DWW company I saw the opposite.

The happiest were the oldest, most established workers, because they had already ticked off all so many life goals, had a house, a dog, kids, etc and so less money and more time was great.

In contrast the youngest workers had no stable housing, and wanted more money more than they wanted time, because they wanted an ability to buy themselves some of those lifestyle things the older workers already had (read: stable housing).

In practice the young workers that needed more money simply used the other day for another job, which was their right.

This was in an environment with a dysfunctional unaffordable housing market, so maybe this all just shows how important affordable housing is and how it eventually starts to trumps all other issues.
