OK, I thought you were talking about the concept, including custom-built Unimog land yachts etc.
Critiquing that brand specifically, I dunno could care less.
But your generalization about very wealthy people is just that. Saying stuff like that says more about you than the group you think you're describing.
I have personally known hundreds over the years from every continent, and there is no one thing you can say about all of them other than the fact they have money.
The majority of them came from money to start with, many just passive income, a mill here or there NBD.
And even many of the very hard-working ones got it just doing what they love, not motivated by getting rich or being overly comfortable in itself.
Many are not "showing off" marking status, don't care what others think, much less other rich people, just love spending on toys and adventure, cool experiences, often putting their lives at risk just for the adrenalin rush of it.
Look at Dick Smith circumnavigating in a helicopter, just doing what he loved.
Now that said, I think society shouldn't even allow that much inequality, but that's a different topic.
