Another protip for them - if you think everyone above you in the food chain is stupid and evil, they notice your poor attitude, because they are not stupid, and evil people exist at all levels of the food chain.
Whether they are stupid or not, they are commonly incompetent. That's why they got made a manager, if their work was so great, people would want them to keep doing it. Then they want to tell you how to do your job, which they clearly were never actually good at, and are even worse now because they're out of touch. There are of course exceptions to this, but I've seen it work this way more often than not.
Evil is almost irrelevant, once you're in the job anyway. Capitalism is set up to reward evil more than competence. But it's the dominant paradigm, so there's no point in complaining about it once you're part of the same system. It's evil all the way down.
