Duplicity

So, once in a while my mind produces an ethical brainfart. I'm thinking it comes from a cousin of the Cow Watcher, since the idea/question comes to me in the same way as most of Cow Watcher's ideas for plots, stories or characters: not quite out of the blue, but finding a basis in a strange concoction of unrelated subjects occupying my mind. I can usually trace down pedigrees or roots of such light bulbs (or halo spotlights in the face interrogation style, depending) but most of the time I don't even want to.

The latest ethical brainfart is:
So, Stephanie Meyer. She's famous. She earns lots of money with crappy writing concerning a subject she confessed (or self-proclaimed) to know nothing about.
I can see where an agent and/or editor grasps the novelty of her ideas with both hands, but surely at one point one of those "professionals" must have also grasped the ideas that while the books are aimed at a public that will easily forgive crappy writing and the novelty would easily make the series a major hit (ka-ching!), the backlash at Meyer's creation and person would be enormous. Let's not forget that the backlash was already huge on J.K.Rowling who at least is a better writer.
The main ethical problem being: agents and editors are all about their darling authors and how they really like to treat them well and have long relationships with them and such, but the Meyer case seems to prove duplicity in motive. While I do find some amusement in the ridicule surrounding Twilight, some part of me wonders about Meyer: Is money enough to ignore (or pay the shrink bills or medication needed to get to the point of being able to ignore) that for every loving fan you have a hateful fanatic? That for every website expressing total love to your creation there's two finding all new ways to mock it? Loving fans are already an image from nightmare hell to me, hating fanatics are ten times worse. How does she get up and/or look in the mirror every morning? Somewhere along the line, one of those professionals that love their author so should have explained the dangers of being a bit of a deluded twit to Meyer, methinks.
Yup, duplicity. Not unlike the duplicity of the claim that they really hope to find excellent authors of novels that will survive the centuries (a formidable task considering the enormous slushpile), but they are simply forced to settle time and again for whatever sells. And this methinks is the logical consequence when you have agents work on commission whilst unable to dictate the market. Or something. It's a bit of a complicated brainfart anyway.
