That is the deceptive thing about KDP Print. They claim the author gets a 60% royalty, but you don't. You simply don't. Period. You get anywhere between zero percent royalty, priced at the minimum sell price, where Amazon still gets their 40% and the remainder is the print cost, which I assure you Amazon is not taking a loss on, and your royalty asymptotically approaches 60% as the sell price of the book increases. It favors high priced books with relatively low print costs. From the author's perspective. Amazon couldn't care less how you price your book.
Even though the pricing structure is punitive, and I make less of a margin on a $9.99 print book than I do on a $3.99 ebook, I feel it is beneficial to offer the option for some to buy a print version if they are willing to spring for the money. And some people are. They just don't sell well enough to make an issue of it.
