I think you inadvertently stepped in the point — Yes, what the fuck do I need 10,000 iPhones for? Also part of the problem is which resources end up in abundance. What am I going to do with more compute when housing and land are a limited resource.
Gary’s Economics talks about this but in many cases inequality _is_ the problem. More billionaires means more people investing in limited resources(housing) driving up prices.
Maybe plebes get more money too, but not enough to spend on the things that matter.
It’s just a proxy for wealth using concrete things.
If you were given 10,000 dollars but your friends were also 100,000 dollars as well, would you take the deal?
Land and housing can get costlier while other things get cheaper, making you overall more prosperous. This is what happened in the USA and most of the world. Would you take this deal?
