I mean it’s trivial to float a scheme in which Jeff Bezos’ max net worth taps out at $100 million and then you have to commit to the idea that no, not only this dude but no one will bother starting a new venture if they can only earn 10% of a billion from it; then since essentially nobody earns that much why the hell does everyone else still go to work.
It’s not that nobody would start ventures.
It’s that when those ventures have produced $100 million of value to the world, they’d stop.
I don’t know when Bezos crossed the $100 million mark, but I do know that I’ve used Amazon this week, so I’d be rather cross with any scheme that killed it in 2007 because somebody was annoyed that a company that produced enormous value was incentivized to provide even more value.
