I don’t think this answer truly internalizes how some of the ultra rich live. Yes, many are living a normal looking life, going to their jobs and doing a lot of the same activities that the upper middle class do. They generally eat at the same restaurants, have the same hobbies, and enjoy the same television shows that the rest of the middle class does. Often they go to the same live events (sports, concerts, plays, stand up comedy) that middle class people do, and often don’t bother with luxury boxes or things like that. They’re members at the same gyms, and might plot out the same run trails as normal people.

It’s just that they tend to fly private instead of commercial, stay at very nice luxury hotels unique to that particular location rather than the chains you’ve heard of. They have multiple homes. They’re members of clubs that require a lot more money to keep up in. They have lots of paid staff, both seen and unseen, smoothing over their day to day lives, washing dishes and laundry, maintaining houses and cars and landscaping, making reservations and doing paperwork on their behalf, etc.

The form of stealth wealth isn’t that they’re all among us doing normal things, with no obvious indicators of wealth. It’s that they often aren’t even around us to begin with. So the sheer amount of time that they’re around non-rich people, and actively interacting with non-rich people, may be a tiny portion of their time. Even if they do a lot of the same stuff we do, and go to a lot of the same places we do. They do it in ways that don’t necessarily interact with us directly.
