I will set a basic standard: Our employers ought not to knowingly violate human rights. Here's a list of some of Amazon's more notorious violations [1]; among the ones that concern us in today's thread are labor rights like the rights to organize, take breaks, be well- and fairly-paid, and work in safe environments.
The point of my comment is not to ask you to defend Amazon, but more to point out the flaw in your worldview to future readers. I admit that I could have dropped many more citations explaining Amazon's poor behavior, but again, that's not the point.

I would generally argue that your ability to change your org is somewhat limited by your profit margins. It is hard to pay warehouse workers more, for instance, if your margins are razor thin. While AMZN's profit margin is not quite the 0 it used to be, it is certainly not stellar by any means. And it is certainly not as good as many, many other companies.
