It's also the case that someone with quite a bit of money doesn't have as much non-work work to do. If you can afford to pay someone to do: all shopping (that you don't enjoy doing), all cooking (ditto), all cleaning (doing the laundry including putting it away, doing the dishes, cleaning your house, cleaning your car[s]), to drive you around so that time's not lost, et c., that recovers a ton of time. You can put quite a bit of that back into your job and still come out ahead in leisure and family time, compared with a worker bee who still has to do all that shit themselves, outside work hours.
