I was invited for coffee at a friend's friend.
He seemed a pretty regular guy, very friendly: kids playing in the pool. Nothing out of the ordinary except as many house employees as adult guests (and house employees where calling guests by their name).
I happened to know the artist Jeff Koons: not a big fan of the "inflated balloon dogs" but I do like his ballerinas. Well... Turns out the dude had one house destroyed then rebuilt to accommodate a 3 meters high Jeff Koons sculpture of two ballerinas.
I don't know exactly but I take it that's a $15m sculpture. I'd say most people don't know who Jeff Koons is and most people have no idea that some people shall just level an entire house just to have an architect redesign a new house, at the same place, so that a sculpture can now be admired from the living room, kitchen and garden.
He's got several paintings from Basquiat too. He's actually in the top 200 of the world's top art collectors (I found that out by googling his name after having been to his place).
And he's got his art pieces sprinkled around the world, in his many properties.
> The $10-30M people don't seem much different from me.
Definitely not very different. One little fantasy I saw not one but two people in that range do is buy several times the exact same car. Identical. Same config. Then they use one as a daily, and put the the others at different vacation places they have: so they land, take a cab, then get to enjoy the same car. Weird but I've seen two people do it, so I take it's a thing? One had identical Range Rover, the other identical Lexus.
Not real petrolheads: rich car petrolheads are actually going to own fancy stuff like old Ferrari 250 (even if "just" a GTE), old GT40, old Porsche, etc. which every body expects rich people to have if they're into cars at all.
But yup: buying x times the exact same car when times comes to change cars is kinda just weird.
