If you're like the other 99.9% of people within the wrestling business who get into it to become a star, build a worthwhile legacy for yourself and get rich doing it, then being a jobber sucks. You don't win matches, you don't get pushed, you don't get paid that well (WWE superstars in general don't make as much money as people think they do, especially after covering most of their traveling expenses and whatnot... Batista even told Jericho on his podcast that until he won the WHC from HHH in 2005, he was still borrowing money here and there from people just to get by), and you're pretty much the bottom of the barrel. There's a reason 'Jobber' is such a dirty and vilified word within the industry. Remember how much Owens and Cody lost their shit when the recent TE winner tweeted [HASHTAG]#TheSocialJobbers[/HASHTAG] (in references to The Social Outcasts) during Raw a couple months back?
Of course being a jobber is a necessary role to fill. So is being a plumber. That doesn't mean you want to be the one that has to do it.
