No one considers Amazon engineers "subhuman" - if that is your perception then all I can say is I think you need to seek therapy for your depression because no one should have to feel like that.
We clearly are - we didn't go to the Olympics, don't have free massages at work or even free first class travel to Hawaii like Googlers do - no unlimited external validation, etc and I make as much as a new grad at other companies. I have literally nothing to show for my hard work. Nothing.
This reads like satire, but on the off-chance you're serious, you need to reframe your perspective. Consider the lives of Amazon warehouse workers, to take the most obvious example. Maybe therapy can help with this.
