The notion that you might be swayed by a true reckoning of the cost basis for a book is thus a little strange. What do you care? If the market price for a popular ebook is $0.50 less than what Amazon is charging, any author capable of writing a popular book could make a mint taking their book directly to market.
I don't believe that the cost of converting from physical to virtual doesn't lead to significant cost cuts. No shipping. No warehouses. No physical shops in expensive locations. No warehouses.
In what possible set of circumstances would you want to discourage people from making you more money?
With physical books, publishers pay for production, freight, and centralized storage for distribution to retailers.
Retailers pay for maintaining their own active inventories, including warehousing and shipping from their warehouse to individual stores, as well as paying for physical retail space.
(And if bookstores don't sell the books within three months, they can return them [hardcover] or strip them of their covers and trash them [paperback] and get a complete refund. Talk about uncertainty.)
Only one actor -- the publisher -- sets the suggested retail price, upon which the discounted price a retailer pays is based.
Show us the numbers then. The publishers won't.
