Yet by every account that mattters it doesn't, right? I understand that people who are there can certainly wish that the place and culture were different in some significant way, but the only barometer that should have some weight is the ease or difficulty that Amazon has in attracting and retaining top talent -- and that to the extent that it is harming their ability to deliver results. Which, from the outside, it certainly doesn't seem to be limiting.

The counterargument is that of course the things which makes Amazon's work culture toxic to people are orthogonal to their success and not a cause of it. My former boss was very well aware that she could sometimes be downright mean and nasty to our staff, and I cringed every time she justified it by citing what people thought the same of Steve Jobs: While true, we can't avoid the fundamental problem of causal inference, and there is no saying that had Jeff been actively striving to make a more welcoming culture, or if Steve or my former boss were nice people, that they wouldn't have experienced even greater success.
