One other observation, was many (but not all) were pretty careless with their belongings.
I had to source 5 top of the range iPads for one in the space of a year because he kept leaving them somewhere (on a plane, in restaurant, just basically anywhere).
Another left two very expensive (talking £50k) watches in a hotel room.
It's just "stuff" that can be easily replaced with no more thought than most people might give to replacing a worn out gap tee-shirt. But there was an expectation that people around them would sort these issues out pretty damn swiftly and if that included flying someone transatlantic to deliver a new iPad (all pre-configured and set up for them) - so be it.
As per my pp this was behaviour generally from the upper end of wealth I encountered and it always reminded me of Paris Hilton who took months to realise she was being systematically robbed of designer clothing/shoes/jewellery because she had so much of it, it wasn't apparent anything was missing for a relatively long time.
I've never been jealous tbh. Frankly I think there's a sweet spot with money where you are super comfortable but don't get dragged into a rarified super lux lifestyle that can actually make life harder in an emotional capacity and badly impact relationships with other people (including your own family).
