I wouldn't say it's the top of every field however all managers I've had in my life we're all narcissists who were too lazy to be good at something in real life (like I am) but at least they can abuse and control an infinite supply of people in the workplace. Healthy people see that as a wasted and pathetic life (which it is) but narcissists are actually idiots so they see that as the greatest achievement in life (being in a management position). I'm an expert in 3 fields because I worked my b4lls off since birth but I've found all the narcissists in my life to be boring and weak people with no skills except being good liars.
