With MMA becoming the fastest growing sport on the planet, many of the fighters believe that their pay should increase.
It is both Nate and Nick Diaz who have openly led this campaign, with the latter almost making a move to boing to make money in the past.
This week, younger brother Nate has opened his mouth about his current pay situation within the leading Mixed Martial Arts company, UFC.
The Ultimate Fighter Five winner has said that he was lied to by the UFC when signing his new contract before his Lightweight Title fight against Benson Henderson, as he is unable to renegotiate with the company since then.
Diaz went on to say that UFC Ring Girls Arianny Celeste and Britney Palmer are glorified cheerleaders who get paid more than him.
The Cesar Gracie-trained fighter was speaking to MMAFighting about his reaction when asked to fight unbeaten Russian Khalib Nurmagomedov.
"I'll take the fight as long as I can renegotiate my contract," he said.
"And then it was all downhill from there. Then they tweeted out that I turned down the fight, and I never turned down the fight. They tried to do me dirty."
"There's a lot more money that needs to be dished out because it's coming in, and I know it."
However these comments have triggered a comeback from his boss, Dana White, who was far from impressed with the comments made.
"Now he comes off a win over Gray Maynard and feels like he should be making Justin Bieber money. Nate needs to get back in there and start fighting, win fights again and earn a title shot again," said the UFC President.
"Guess how much money he makes sitting at home? Zero. Get back to work, Nate. He was happy as can be when he signed his new deal. Go back and look at my twitter after he signed the new deal. I tweeted it. He was happy. We've done everything to honor the contract. I've always been good to Diaz.
"This is the kind of craziness you see with athletes. They end up spinning off and don't make the money they should have made. Nate Diaz has what it takes to be champion or he doesn't, but I'll tell you, there's only one way to find out.
"He has to come back and fight. He thinks he loses to two of the best guys in the world and deserves more money? In what f*cking planet does that make sense?"
We are in an era of MMA where more money is becoming involved everyday. The UFC is a household name and has multiple shows, yet it seems the fighters on the lower end of the UFC are not making the money they should. Fighters such as Tim Kennedy and Nate Quarry have recently talked about fighters pay.
Even if you compare the elite in MMA to boxing, it seems harsh. Whereas Floyd Mayweather makes around $30M a fight, UFC Light Heavyweight Champion Jon Jones apparently made around just $700,000, with his opponent Alexander Gustaffson making just $80,000.
It seems that the UFC are trying to deal with the situation, however. They are planning to introduce 'Fighter Uniforms', where fighters will be fully attired in UFC-branded clothes. They believe it will promote the brand name, which will bring more PPV buys, leading to more income to pay the fighters.
