Companies like Amazon can pull this off because of stock grants. (And I don’t think they give out stock grants to warehouse workers, but I could be wrong.)
When they hire a developer, especially one who already has the relevant experience they for, they will say “On top of the salary and bonus, we will also give you $200k worth of stock”. But that stock can’t be sold right away; it goes into an account where it vests over some number of years, every 6 months. Your only condition for vesting the stock is being employed. If you leave for any reason, or even get laid off, you give up the rest.
Sometimes you also get smaller awards with your yearly review, subject to the same terms. They do this so that if you are a key developer, leaving would mean you forfeit this large account you have accumulated on paper. But in the back of your mind, you know that if your project gets canceled and you don’t find a new one in the company, that money goes poof also. So it’s play money until it vests, anyway. And there is always another vesting event coming sometime in the next few months.
