You've just described the job market. If this employee cannot find better paying employment (assuming that the job market is operating efficiently) then it is either a skill issue (This hypothetical employee is not sufficiently skilled to demand a higher salary) or a demand issue (There is insufficient demand for your skills in the market).
We can have a fruitful discussion around job market efficiency (e.g. is Amazon a monopsony employer in some local markets), but objecting to the tone of the comment feels very out of place when this is the language that we use to describe the economy.
I really can't think of a more apples-to-oranges comparison (pun not intended). The only thing Apple and Amazon have in common is that they're the A's in FAANG.
How would the FTC going after Amazon help these people?
