Try this fun game.
Imagine you live a hundred years.
That's 36,500 days.
Imagine you get to spend 20,000 dollars a day, every single day.
Yup you're a newborn spending 20 k a day, stay with me.
You'd die a 100 years later and you would have spent 730,000,000. That's 730 million dollars.
You still would not be able to call yourself a billionaire.
Billionaires should not exist.
