I'm sure if I was the lottery winner I'd be salty in this scenario, but you only get half as a lump sum anyway, and having $1 billion taxed at roughly half is probably how it should be.

The thing that makes it painful is as OP said, all billionaires should be getting taxed like this, not just that one who can't exploit tax loopholes.

OH NO! Only $424M USD?! How will he get by?

I'm kind of surprised the USA taxes lottery winnings and I live in one of the heaviestly taxed countries. We don't tax lottery winning or other winnings from games of chance. Only winnings from games where some skill is involved (like poker I believe) is taxed.

I can tell you what I would do with $424m, disappear. I'd still do good with most of it but I'm going to leave human society and go join a herd of elephants.
