Kinda of a side note but a way I try to talk to people about how much a billion dollars is is "how many people can you hire each day at X dollars before you start losing money".

Here's the setup: you have a billion dollars invested in some account earning some interest, let's say 5% because that's like bond rates (lower than S&P500). Day 1 you generate interest and don't hire. All following weekdays you hire a new employee and day then daily at a yearly rate of Y, say $250k/yr. Most people are going to be surprised that you can basically go an entire year before your account has less than a billion dollars.

I do this because it's so much money the daily interest is not negligible. I mean 1000000000*0.05/365~=$137k. Is back of the envelope and estimating, but it gets the point across. (So you can hire people daily at $100k indefinitely...)

Anyways, googling suggests there's ~600 American Olympians that participated in 2024 and another ~250 paraolympians. So what, we need on the order of $10bn to solve this? I can think of a lot worse ways we currently spend that kind of money and about 15 Americans where this would be less than 10% their total wealth and 11 of those people made more than twice that just last year... I'm not saying anyone should but hey, Elon could solve issues like these without blinking an eye. Probably better PR than anything else he could do

Your illustration is really long winded.

If you invested a billion dollars at a conservative 5% interest rate, you could employ 200 people at 250k a year on the interest alone.

You'd need to account for inflation right?
