First of all, many (most) of the people who work at Amazon are not engineers or managers in a position to "negotiate", and don't have "somewhere else" to go to work and get the money they need to eat. They cannot "renegotiate after signing", which in these situations is something traditionally done via worker unions, which Bezos has worked very, very hard to disable.

Second, without the workers who, according to you, don't deserve any credit, Amazon (the entire thing) wouldn't exist. These "right people" Bezos hired were workers, and hiring them is not what built the company. "Starting a company" is not exactly hard work. And he didn't personally provide the compensation and benefits out of his own pocket (besides the first 300K "from Jeff Bezos and his family" according to Quora), it was always investors' money, or the money generated by Amazon itself (who was running thanks to these people being compensated). None of these things are usually talked about, it's just Bezos and Amazon on the news. Do you really think that "the workers" are getting too much credit, when they never get none?
