> most people don’t get significantly happier after 75k or so a year
I call hard bullshit. Without even considering luxury spending, just not having to think about money very often is incredibly nice, and $75k is nowhere near any kind of plateau on that.
At $75k you had damn well better still be tallying up how much money's going in your cart at the grocery store. Not having to do that for basic stuff anymore, not having to worry much about coupons or bargain-shopping and just being able to say "I need this, or at least it would be very nice to have" and get it, no worry, no saving, no waiting for a sale, is such a GIGANTIC load off one's mind.
Car breaks? Take it to the shop, any plausible bill won't trash your budget for the month, let alone the year. Water leak? Yeah you could fix the drywall... but if you really don't feel like it this time, or are busy, you can just have someone else do it and the bill won't sting that bad. Groceries? Barely even pay attention to the total. Need some particular clothes for some purpose? Just buy them, and decent ones that won't look like shit and do fit right, at that. Kid breaks their arm? The cost barely even crosses your mind (it'll suck, but you'll be fine).
It is SUCH a relief.
