If you are rich "outsourcing" is easy because you have people to handle that for you. You have senior servants like butlers and housekeepers who manage the rest of the staff, for example, so you are not directly hiring cleaners.
This is the difference between the affluent and the truly rich.
It's fair that's probably the difference. You don't have a full-time personal assistant/butler/whatever you want to call it. But you personally outsource a lot of individual tasks that you don't really want to do.
In this day and age, how often do you actually need to have your car serviced? And there is no shortage of places that will do it for you in a few hours.
Similarly, if money were no real object within reason, I'm not sure what I would really need done on a day-to-basis that I couldn't just order or contract for pretty easily.
You clearly don't have enough cars. Once you get enough cars, especially if any of them are classic cars you actually want to drive occasionally and want to be in a driveable condition, you might want to have a full time mechanic.
