>Maybe I'm totally wrong but if I am, a whole lot of people who aren't you are too.

You believe the version of the world that they want you to believe, not the world as it is. That's understandable. The powers-that-be project this narrative specifically because if people know their job is to manipulate feelings, it'll be much more difficult to do that effectively.

Good managers want to make themselves sound like self-sacrificial superheroes and inspire hero worship so that it's easier to manage the subordinate's feelings. That's the narrative they project.

However, it doesn't take an intelligent person much reading or experience to realize that things don't line up with the narrative. Management is all about managing feelings. Yes, it's true that management has to make decisions that won't bankrupt the company, but that's the easy, minor part. The difficult part is pushing those decisions through the organization with as little feeling-damage as possible, and running programs of feeling-grooming to keep your employees cooperative.
