I have an amicable solution. Don't let big publishing be a cartel setting prices willy-nilly, and if it bothers him that Amazon or whomever wants to have a sale on a book, they can negotiate a "bulk buy" of the paper or ebook with the author or publisher and then discount it however they choose. But, he's insane if he thinks collusion is the answer.
