Depending on the person, that may be a good motivator for them to not seek more money, but to seek more time instead. I'm certainly there. I've turned down more money when the position would mean that I was responsible for an awful lot more and it would take time away from my kids. When they're older and possibly out of the house, that may change, but for now? I'd rather have the time than the money because, like you, I have "enough." It's just not a limiting factor at this point in what I care to do, but time is.
