I'm not 100% sure what to make of that post but its all prize fighting. Look at someone like Floyd Mayweather. That man makes like $40 million a fight. In a broad generalization, he does the same thing as any fighter in the UFC. When you are a fighter you are your own personal business. If a company is going to make millions off your name and you putting your body on the line, you should get a decent cut of it. Obviously champions and bigger draws should be making more money than the guy that is a relative nobody fighting for the first time. But think of it this way, the more important you become in your own personal line of work, don't you want to be compensated for it or are you happy never getting a raise? Everyone wants to make more money and someone like Urijah Faber, who is a face of MMA, should be paid accordingly.
Now to break up another point you tried to make in your argument. You aren't necessarily making $20,000 just for 15-25 minutes in the cage. If you look at it simply that way, I could partially see your argument. What you are making $20,000 for is 8-12 weeks (sometimes longer) of putting your body through physical hell in order to prepare for an athletic contest that requires you to knockout or submit your opponent while he is trying to do the same exact thing. You aren't getting paid while you train and you aren't getting paid by your company while you are not fighting.
Let me put it in perspective for you. A guy fights on the very first card of the year. Lets take the UFC for example as there is a card litterally on January 1st next year. He fights and loses. So he only gets the $20,000 to fight and loses out on that win bonus that would double his pay. Now he has to heal from that fight and probably won't be schedule for another bout for atleast 2 or 3 months. In that time, unless he is doing something else for income, he's not making any money. Sure he's probably still training, but he's not bringing in any income. Then he gets the call for his next fight in April. He's training his fucking dick off for it and gets hurt 2-3 weeks out from the fight and has to pull out. Well there goes that potential $40,000 he could have made (thats if we're still sticking with the even $20,000). So now he has to heal from that injury which could be any number of weeks of. He then has to get himself back into some shape prior to even thinking about dedicating himself to an 8-12 week training camp. So now we're probably around September, still riding off that $20,000 from the fight on January 1st. So now that he's been out of action for awhile he's low on marketing, which means lower purse for this next fight. Now he's fighting for $15,000 to fight, $15,000 to win. His fight is in November. He loses. He won't fight again in 2011. He's made $35,000 for the year.
I could go on about how technically he doesn't even make $35,000 because of taxes, paying trainers, paying for physical and license to fight, and manager's percentage. So after that we're probably looking something in the realm of $15,000 and that's being generous. Sure he makes money on sponsorships but if he's an undercard fighter, he's not making that much from them. And that also gets broken up by all the previously mentioned stuff.
