I agree with you, but what would be the argument against Athletes and someone like J.K. Rowling (Harry Potter author)?

The chart on the site below shows JK Rowling's net worth growth was pretty much linear. $100M per two years until about 2006, then $100M a year after that.

She also pays full UK tax on her earnings, the 36th most of any individual.

But that's not a response to my question.

It is in the context of this thread, because the article is about exponential growth.

Founders are often synonymous with their businesses. In the case of celebrities the relevant exploitation is carried out by others in the value chain, they are just the lure/source.

There's no such thing as a billionaire athlete. There are a handful of athletes who went on to become billionaires through their business dealings, like Michael Jordan, or Ion Țiriac or LeBron James. The arguments are exactly the same for them as for any other billionaire - that their businesses are either not really worth as much as the numbers suggest, or that their business engaged in various problematic practices.

For authors, the arguments are again quite simple - billionaire authors or directors don't become billionaires by selling books or movies, they become billionaires from much larger businesses that employ way more people who were collectively much more critical to the success of said businesses than the authors themselves. JK Rowling didn't become a billionaire until the movie franchise and the toy mega production began. If the movies hadn't happened, or the toys hadn't happened, she would have just been an extremely rich multimillionaire.
