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.
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.

Companies exist to make money period. Look at the most powerful companies throughout history (British East India Company, Standard Oil, Goldman Sachs, Walmart, IBM, Facebook, Google, Apple ect). Do any of these have as good of a record as Amazon? IBM for instance played a major part in the Holocaust. Goldman Sachs was involved in the scams crashing the world's economy. Facebook and Google prey upon people's addictive behavior and use it to sell adds. Apple simply has all their employees run out of sweatshops in China, and has all their tax havens in Ireland.
I'm for workers rights and for people getting more pay, but let's be honest, expecting Amazon to fix our inequality problems is astonishingly naive. If Tim Bray wants to leave to have a good conscious about it - that's fine. I myself would never work for Facebook or Google because of how they addict people to their phones. We all have our own standards, but not our own facts.
