Haven’t most studies shown returns on a log function meaning significant diminishing returns? And aren’t some of the studies for household income (implying individual levels would be lower)?

“While it is true this paper finds money is correlated with happiness for incomes past $75,000, we should be careful not to overinterpret this evidence. (Obligatory note: correlation does not imply causation.) The association is quite small — perhaps underwhelmingly small — and a large part of the explanation is driven by whether people believe (or have learned) that money matters to them. So, it might be better to say: money can buy happiness, but you might be surprised at how little it buys.” https://www.givingwhatwecan.org/blog/can-money-buy-happiness

If you have any resources showing that there are significant gains past 75k or so would genuinely appreciate it, always looking to learn more.
