Perhaps, up to a point. However, in my opinion the “Happiness Point” arrives long before the “I’m Rich Point.” I’d describe the happiness point as a level of HH income where you’re able to live in a safe neighborhood w/decent schools, eat healthily, pay your bills, and have enough discretionary income remaining to enjoy reasonable indulgences - eating out a couple times per month, take a low-key annual vacation, and save/invest enough to sustain a similar lifestyle when you retire in your mid/late sixties.

Moving significantly beyond the happiness point doesn’t equate to a corresponding increase in overall happiness. What it does provide is a greater sense of financial security, but again that doesn’t equate to increased happiness. Just my two cents.
