I think that, somewhere north of $1 ~ $5 million is life-changing on its own. There’s no need for someone to have tens of millions or hundreds of millions. Tens of millions is like, changing multiple lives in a family with how much that can stretch.
Whenever someone has billions to their name, it is boggling to think about. That it becomes just ‘fuck you’ money at that point because more often than not, not a lot of billionaires out there being charitable. When they know they’re set for a few lifetimes just by a single billion alone.
No single person should ever have that amount of gross wealth.
When you say “make”, do you mean extract?
I’ve heard Wall St destroy over 7 times as much wealth as they “make” from us.
I’ve also heard salaries over $£€70,000 no longer increase happiness. (Though, that was a few years ago… so, adjust for devaluation.).
More than what should a UBI be set to, if all the emancipatory technologies ceased being suppressed, and instead were proliferated to the benefit of each and all… would we even need money any more?
