(The people I've known with serious money made most of it themselves, and didn't need a family office. Except for one married couple who blew through 8 figures and went broke.)
These are between multi-family offices and scams targeting new money. (The intersection between the best hospitality folks you can privately hire and the best money managers is roughly zero. Consolidating those functions makes no sense unless someone cannot afford them.)
That's a good way to look at it.
Now Ryan Bingham doesn't command any particular status or wealth, but he makes a living firing people on behalf of other companies ("Concierge firing-as-a-service"?) and he leads a nomadic lifestyle that many of us would find completely intolerable.
His one lifelong dream is to earn 10,000,000 Frequent Flyer miles and hold the special Unobtanium card from American Airlines. [SPOILER WARNING] He achieves this during the final flight of the film, and when he dials the number on the back, he comes to realize that this is his unique number and there is a specially-assigned staffer waiting by the phone to personally take his call.
I can envision this sort of revelation as the experience of someone who comes into money and suddenly finds their needs being personally met by a concierge or family office.
For small values of "personally". I once visited a rent-an-office place which had a live receptionist. She had a phone with about thirty line buttons. Each time she answered a different line, she gave a different company name.
