"The whole point is that no human, not even Jeff Bezos, can generate 200 billion dollars worth of value by working"

This is untrue and unlikely.

Invent a star trek type transporter. I bet you could sell your work for 200 billion in cash or 1 trillion in fedex stocks.

You are never going to create 200 trillion value working for Jeff so he pays you 200 billion. Amazon is setup so the value create goes to Jeff and other shareholders. If you are lucky you get 100th of the value you are part of creating. (Yearly profits + yearly valuation increases) / total employees / 1000 is your pay if you are lucky
