Just to be clear: My main point of sharing this article is about how detached the life of rich people is.
I do not at all agree that most of them are “Not evil, just disconnected”, I am pretty sure (and know some of the privileged), who are actively evil, know exactly what they are doing and just don’t give a shit.
To be fair, if they really were just living lavishly and not using their wealth to amass more wealth like some kind of wealth black hole, then the extreme expenditure of such a lifestyle would one day drain their money dry, since they couldnt possibly actually earn enough to live like that. Were it not for the effect of wealth begetting more wealth, the issue you refer to would eventually solve itself.
This why we start taxing at 100% over a certain amount. They can keep living lavishly indefinitely while everyone else gets to benefit from putting money to actual use.
