Nothing sends Miss Snark's chapeau into spontaneous combustion more quickly than: "this popular novelist got it all wrong; it's time for the REAL story to come out."
For starters, if a novelist is popular and selling well, do you really think her readers are going to come on over to read you debunking her? noooooo.
If a novelist is popular and selling, do you think it might be because ...oh my dog, the concept...people LIKE the stories?
If you are moved to put pen to paper to right the tragic misconceptions of a series of novels involving an industry or a profession, and MOST particularly if you are writing to illustrate a bone headed political situation, hear this now:

You simply cannot expect a book to be taken seriously if your major goal in writing it is to "prove" (via fiction no less) that Jan Karon's Mitford series is all wrong; that Laurie King's Sherlock Holmes books are all wrong; that pedophilia is bad; that puppies are good.
Novels are about stories, and they have to be filled with compelling characters. You start yammering at me in your cover letter about the life lessons I will learn by reading this tome and you've got a lesson in what's not right for my list coming right back atcha.
