Does he write his own books, though? [0] [1] [2]

It's his name on the front of the book, but he is not necessarily the primary author. That sounds a little unethical to me.

Stephen King then? Or J K Rowling? They became billionaires off their work and wrote all their own work if image rights are unethical to you.

Taylor Swift, perhaps? Paul McCartney. You only need one example to disprove the case.

It doesn’t seem ridiculous that if you make something and charge $10 and 100 million people pay you that you’re necessarily doing something unethical.

I don’t think any of them have done something unethical to earn their billion, but artist billionaires are certainly outliers.

They’re such outliers that it’s still a safe assumption someone has done something exploitative if they’re a billionaire.
