A generous attempt to disentangle exactly what Bill Gates meant by saying he'd pay $100 billion in tax. I think it's a fair point that Gates meant over a lifetime, but.....
...but even if what Gates is saying is that he'd pay $100 billion over the course of a lifetime (if he lives to be really, really old) the math still doesn't work. Because the money he has would be growing as well. He'd still be one of the richest men alive.
Citizen Kane: "You're right, I did lose a million dollars last year. I expect to lose a million dollars this year. I expect to lose a million dollars *next* year. You know, Mr. Thatcher, at the rate of a million dollars a year, I'll have to close this place in... 60 years."
Gates is like Charles Foster Kane but even more extreme. He could lose $3 billion a year every year for many decades before becoming a mere multi-billionaire.
But the best comment on all this is from a Tik Tok teen:
