That is why 'my needs taken care of' issue comes up to me. Yes, 100% of the jobs I worked paid me enough to have a decent life, but if I got fired and couldn't find a job, I would be on the street after a few months. That is why the 75K USD or whatever it was in the book saying it didn't improve happiness is bollocks. You might not starve in SF with 75K, but I assure you an extra 20k would make you much happier, even if not for the peace of mind that you could save it for a rainy day.
If we talk about UBI or millionaires, sure, money stops being a concern, but I also don't see a lot of millionaires going over job boards trying to find a job that gives them a sense of accomplishment. They are doing their own things to achieve that happiness, and I doubt is working for someone else (some exceptions of course)
