It's all relative: 600 thousand seems a lot for a single fight, but if that man's PPV sold comparable PPVs as a Pacquiao fight, then why does Pacquiao get 25 million for a single fight? And Mayweather too though he gets no endorsement money because of his multiple convictions for beating women.

...because dana white and the fertittas make millions each show on the backs of the fighters who risk their health, that's why!

Boxers a hundred years ago were making what top UFC fighters make right now, and I don't mean adjusted for inflation...
