"I think that they should get paid more than the ring girls," Rousey said when promoting UFC 184 at Glendale Fighting Club."
"And I don't know if the ring girls get paid too much or the fighters don't get paid enough. But yeah. There's definitely a lot more in what the fighters do than what they do. So, I think that's one thing that's unfair."
Rousey, who defends her women's bantamweight title against Cat Zingano in the UFC 184 main event on February 28 in Los Angeles, disagrees that fighters have no financial leverage as free agents, because the UFC has eliminated its biggest competitors, saying the UFC's most significant rival is owned by a huge media conglomerate.
"No, I don't think the UFC is a monopoly at all," Rousey said. "Viacom owns Bellator and they have way more money than the UFC does."
The UFC is actually a sponsor of Rousey and she also just landed an endorsement deal with UFC apparel partner Reebok.
"I have a comparison with how I was treated as an Olympian to how I'm treated as a UFC fighter and I always feel like I'm just so lucky to work with a company that I feel like actually cares," said Rousey.
"There's times where they give me more than they're contractually obligated to or more than I even expect. That's why I always trust them so much. Even if they didn't ever give me anything extra, I would still be happy, because you know what I made an as Olympian? Nothing. It cost me money."
Rousey, 28, said she doesn't need that much money anyway. She never intended to get rich doing MMA.
"I've always been very well taken care of," she said. "I'm always extremely happy with how I've been treated."
