Any notable plateau is assuredly way over $75k. Not being anywhere near as stressed, and spending at-most 5% as much time thinking and worrying about money as I did when we were struggling, sure frees up a lot of energy and time to pursue happiness, if not providing it directly (i.e. not even counting when I'm able to trade cash for things like free time to play with my kids or spend more quality time with my wife, let alone buying toys, which, hell, is also genuinely nice). I'm certainly grateful every damn time we have some mid-tier emergency pop up and the part of my brain dedicated to money just goes "hm, that's a shame" and then shuts up, rather than screaming "OH FUCK OH FUCK OH FUCK" for a day or three. It'd be madness to suggest there's not a strong correlation between that relief and general happiness.
