Except that's only how it works mathematically, not in practice due to human nature. Perceived value of money would be something really interesting to study as there's just so many variables of which wealth is one, but I'm not even sure it's the most important when compared to upbringinging, source of money (do you work for it, even if you're overpaid, vs winning the lottery/being a parasite like selling mineral rights or buying properties and getting a management company you're not involved in to rent them out etc.) and others
