What if the warehouse workers outnumber the tech and managers 100:1? With >1 million employees, that ratio is likely pretty steep, in which case, even if all managers and tech workers were paid zero, it still wouldn’t move the needle for everyone else.

Because it's spoken like someone who has never dealt with human resources inside a company. The people making more money have more options - they'll just leave Amazon.

Each role has it's own supply and demand. You can arbitrarily start paying less for a role and not expect there to be a negative impact.

You (and others, evidently) don’t pick up on the tongue in cheek nature of the comment. We all know we can simply raise pay at the bottom without needing to cut (or inflate) anyone else’s pay. They are similarly absurd propositions.
