I scoff every time a cop on a TV show is like "I joined the force to save lives and make a difference" because it's painfully obvious that this is pretty much never the case in reality.
I feel like CEOs are more like football coaches in terms of job security. As long as they keep winning, just about no form of misconduct can dislodge them. Stop winning though, and the hot seat can become very uncomfortable.
But they make so much money and get huge golden parachutes so they have more money than they would need for the rest of their lives, and yet they still are able to get other CEO jobs. It's a little club and once you're in, you're in.
