This really shows the book publishers are fools. For a physical book, they only make money when it is first sold. The author only gets royalty when the physical book is first sold. That book may change hands (perfectly legally) hundreds of times after the first sale and neither the publisher nor the author get a single cent. An eBook on the other hand can only ever be sold once legally as there is no way to legally transfer ownership of an eBook. If 100 people want the eBook they each have to buy it (or get an illegal copy). Given production and distribution costs of an eBook are significantly lower, an eBook should be way cheaper. Maybe one day they will wake up.
Maybe there is more than foolhardiness at work here....are ebooks not more convenient than carrying around paper based editions? Should that convenience be reflected in the price? And perhaps the price of an ebook is set, knowing that some will share and share their ebooks with the many...charging all for the actions of some to ensure the revenue earned reflects the infringing?
Secondly, the price of a book isn't really based on paper, bindings or pixels. Its the value of the information contained therein....is that what makes something have monetary value, something worth paying for? After all, if something has no value, don't we all look elsewhere and buy something else? Camera kit, cars, houses...food...the information in books...we can choose.
And besides, copyright gives artists a monopoly to exploit their works they see fit. This can include cheap, middle ground or reassuringly expensive. We can buy, or not...if the masses stay away the price will fall...all the time plenty are handing over their cash the market will be sustained.
