They force books in the 3-10 price bracket to artificially keep the eBooks cheap. Authors in the KDP program will lose money if they charge between ~10 and ~20. It doesn't matter if as an author you have a book that should be priced above 10, you're pushed into charging a lower amount. This ends up benefiting low-effort books because the ROI on them ends up higher than more complex projects that would require charging more per unit. Selling books is a tricky business and Amazon is helping itself more than it is helping the ecosystem. If you can choose, go to a different vendor for books, preferably buy direct from the authors. My own personal choice is first attempting to buy direct and my second option is Kobo which has a better royalty breakdown and is curated by real humans, as in as an author you can reach real people to talk at Kobo and help you out.
