I feel a better analogy would involve (A) a demand that is outside the official job-description or duties and (B) isn't a fixed-bar but instead makes multiple employees fight each other in an indefinite race to the bottom.
Ex: "Are you willing to spend your free time becoming the General's #1 personal servant? No? Sorry, there's no place for you in the infantry."
I don't find better but more vague perhaps in attempt to sound nuanced.
If one goes by job description Amazon is acting strictly within those parameters. And that race to the bottom is not really hunger games.
On the other hand if one goes by unsaid rules of games, everyone including management, HR, employee know FAANG salary is multiple times of equivalent IT workers. And perhaps 95% of FAANG employees are not really developing new algorithms, hauling terabytes of data on their shoulders or being the force of good whatever that means. Just keep doing made-up work and wait until reach x million dollars goal. After that leave quietly or loudly by writing a nasty blog post lambasting management.
So mostly people understand they have to keep up the facade because talking about what's really happening will make it rather awkward for everyone.
