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.
Wait, wut?
SpaceX has advanced what humanity can do in space by a significant amount. It achieved something no government was even considering attempting until they proved it possible.
Google has added some massive value to the world, making information more accessible and advancing hundreds of other services and companies. From Gmail to Waymo it too has advanced humanity significantly.
