A person that has 1 trillion dollars or makes multiple billions of dollars a year, probably only needs $100K per year during their rich lifetime to make them "personally comfortable".
That speaks NOTHING of the extra billions that NEVER EVER need to become liquid to pay for the things that keep them in power, pay employees, buy homes. I think the person that wrote this piece is forgetting that it SHOULDNT be done this way. I don't care if it's the "way all the countries do it" of course it is - the rich copy and paste the rules that work for them across the nations.
