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.
A house, a car, and enough to pay all the bills and still have some lifestyle, without the terror of knowing you are one job loss away from homelessness and starvation. Able to retire for 25 years before dying.
I think for us (a family not a single person) that really is a million in the bank and 200k per year. We don’t have that, nor do many others.
As a cap? I think nobody needs to accumulate more than 5 million in cash and other assets. Less if you live somewhere with reasonable pension and healthcare.
