BBC News article on big name authors like Wilbur Smith using co-authors (uncredited) for producing more books per year.

Coming from an engineering background, I don't understand why there is so little collaboration in the creation of novels. Pooling ideas and talent, where one author might be better at constructing prose, another dialogue seems obvious.
Doing it just to speed up production and you lose that hand-crafted aesthetic
What I find interesting about this situation is that, as far as I can tell, most readers don't seem to mind very much. No longer is the writing the product. The Big Name has become the product.
I grew up reading the Hardy Boys and Nancy Drew - I didn't and still don't care that Franklin W Dixon and Carolyn Keene are syndicates.
I agree the tactic stinks. It is not, however, underhanded as the co-author's name is right on the cover with the Big author's name. They are not hiding the fact that it is co-written, so no one can claim ignorance. And anyone with a lick of sense should be able to figure out that the co-author is doing most of the writing. How could the Big name suddenly triple their output otherwise????
As I mentioned above, what has happened is that the author has become the product. Not what they write.
