No, strong disagree. Combat sports to popular-culture sports is comically NOT apples to apples, so I'm not getting your point.
However, if we're going to compare incomes, 30mil (x2) is a fuck-ton of money and puts Jones in the 1% of the planet pretty much. Not sure why you or anyone else would think he should make more. Meanwhile, NBA and footballer twinks are raking in even more, which is also absurd and a cancer on society. It's like people don't understand the diminishing returns of having more than 50 million dollars, or the numbers are just too big so people subconsciously think that there's a difference in quality of life, whatsoever, between people making 10 million and 60+ or more. Obsession with wealth is weird, especially considering it's almost always coupled with a complete lack of understanding.
