No, I'm sorry , this is just wrong. There are plenty of things wrestling and "regular jobs" have in common. The big one is politics. Politics is everywhere. It's always a good idea at any job to be well liked by your peers and superiors, whether or not you actually do a good job. Also, there's plenty of backstabbing going on, where a supervisor may not promote someone simply because he doesn't like his "style." If you want to get anywhere at your job, make someone high up on the totem pole like you and more importantly don't make them not like you.
And don't give me that "Well, London and Kendrick work their asses off and are just jobbers! Vince takes one look at Kahli and wants to make him WHC!" That stuff happens all the time in real life. Bosses always have their favorites.
