When you say that music has to be produced, maybe you don't realise that books have a simliar process called editing. As a musician, I know how much work is done in the prouction box and how much in the studio, but knowing writers, I also know how much can be contributed by a good editor. They both cost money, as does the marketing to get people like you to know that the book even exists. I think I'm right that Stephen King's attempts to sell a book online only, chapter by chapter, failed because people weren't paying for it. If a blockbusting seller like him can't do it, why should other writers and their publishers be forced to make an even smaller profit from what is a lot of hard work?
