Floyd scheduled to make $41.5 million...as a starting point.

Awhile ago I thought about how the UFC, MMA's top organization, screws over its fighters with their payroll. I know boxing has had its share of that but all in all boxing pays over 50% of its revenue to the fighters which is fair and on par with the other major sports organizations like the NFL, MLB, NBA, and the NHL. Meanwhile the UFC pays out approximately 4% of its revenue to its fighters and thats with their bonuses. Meaning...a rough calculation and projection of just Floyd's minimum for his next fight will be more than all of the salaries of all the fighters combined for all of the cards combined on UFC 165 to UFC 200!!! Heck, even Canelo's minimum will net more than the fighters' salaries on the next 7 UFC cards. Even though they deserve it I think boxers are in a good place with the market rates of their talents/stardom. Curtis Stevens, a C or B lister at best so far, rejected the first offer of 300k for Golovkin and presumably got more as the fight is now on. Delvin Rodriguez just turned down 800k for a Ward fight because it wasn't enough for him. In comparison, Chris Weidman got 96k (including his win bonus) for taking on and beating the GOAT of MMA in Anderson Silva. All of this lead me to a question...should boxers be criticized a bit more for turning down fights or be happier with their pay? I know some boxers still get ripped on the regular and some are getting jobbed with the higher end percentage take from their promoters so I'm not disregarding that but I'm speaking all in all. Its clear MMA is a companies' market but is it fair to say boxing is in a fighters' market right now? If so, I think its great but how did it come to be?
