These "if you saved this much every x number of whatever, you still wouldn't be as rich as y" are so goddamn stupid.
Its like really? Your telling me if I did nothing but hoard money for the sake of it, I wouldn't be as rich as a guy who actually does shit? Wow.
Oh and the math is wrong, because of course it is.
Elon is worth 289.7 billion or 289,700,000,000. And this is all wealth. Not liquid cash that can be spent at a moment's notice.
82,021 years equals 29,937,665 days.
10,000 a day times 29,937,655 equals 299,376,650,000 or about 9 billion more.
