Given human nature I find it hard to blame rich people for using their money on themselves. We need laws to change (aka much, much higher taxes)
Someone’s perspective on what’s an appropriate standard of living changes with what they’re used to. That’s just how the human brain works. I constantly hear people that make the same or more than me, that live in the same country as me in an area with similar cost of living, complain about how little money they have, while I feel like I have all I really need and more. They just consider different things as “necessary”.
Is it incredibly disconnected to consider owning even one yacht as anything close to necessary? Absolutely. But anything you want, your brain will take it for granted once you get it and make you want even more.
