Ahh. I meant in the sense of diminishing returns. E.g.: one person with $1B vs one person with $1M. The first million can really kickstart someone's dream life, whether it's repayment of house or car debts, purchasing lots of items, funding a hobby and/or business, or travelling to exotic places. On average, each subsequent million has a drastically smaller effect on overall "quality of life" than the previous million
It is called the law of diminishing marginal utility that you refer to. Diminishing returns are about the decrease in the output of a production process...

Sorry for nitpicking...
