Every time I read a thank-you "to my [Acquisitions] editor" in the Acknowledgments section of a book I'm editing, I want to scream.
The acquisitions editors bring in the work (quantity); we copy editors bring it up to publishing standards (quality).
Publishers should have a policy, written into their contracts with authors, stating that in the layout stage of a manuscript they will insert a standard shout-out for the copy editor and proofreader.
