I think the cause and effect here are reversed. Thing is, in a society like ours, you pretty much have to be a shitty human being to become a CEO of anything even remotely big. It inevitably requires walking on heads and abusing people to the extent that no moral person would be comfortable with.

So we have a system that puts selection pressure on economic elites to be sociopathic. And then those same people write the books on "how to be a good CEO" etc, so of course they are going to say that you're not supposed to do things that they themselves don't do.
