i dont think this guy was complaining as much as admitting to himself "ya know, Im never gonna be champion, im never going to make GSP money in this business, so Im going to hang it up now and do something that I make more money at". and thats not crazy. ive left jobs for better paying ones.
and I like what Chael said even though he wasnt talking about it in this context when he said "this is a volunteer army". no one is forced to work for the UFC. no one is forcing these guys. the bottom tiered guys just get a little piece of the pie and a CHANCE. not only that, but having 1 fight in the UFC can change a lot of other things. you open a gym and say you are a "UFC Veteran", people will pay twice as much to train with you.
in closing, no sympathy from me. these guys aren't slaves. if they are passionate and hard working and able, they'll take the bumps in the road and work their way up. if they cant go up, they should be smart like this guy and do something else that pays off better for them.
