If you got 10% it would be 50 years
Warren Buffet is definitely impressive, but compounding capital is a huge benefit
(Ok ok I ignored taxes, inflation blah blah)
Edit: just because this is fun: at $365M a year, you get WB wealth in 50 years at 5% and 32 years at 10%
Edit2: if you take Berkshire Hathaway's historical annualized return (20.8%), compounded quarterly, starting with $52M and no additional capital after that, you get WB wealth in 36 years.
Also proves out the opposite though too. Buffett, and his kids could spend $1 million a day and never run out.
That being said, it's also very fragile in a way. Not having skills or a wage means your wellbeing is subject to the overall economy. A lot of multi-generational fortunes were wiped out in WW2 and the great depression and never recovered.
Another billion or even $100 billion isn't going to change Warren Buffet's life at all. In fact he'd probably trade it all just to be young again.
