i dont blame them i dont think its fair for women to make as much as men for one women on average make it to ufc in half the time as most men due to lack of competition they arnt near as skilled as men on the average most women i see turning pro in 2 -3years when men on average 4-7 years training . same reason womens nba players dont make near what men doYou have to be either beautiful or on top. UFC had absolutely ugly female champs before earn good money.
To earn good money as a dude in the UFC you need to be on top too and that's a lot easier said there done.
Imagine the amount of technical advantage you would have to beat say Yoel Rommero.
