I have an article in the hopper for next year, and the publisher recently inquired if I wanted to release it as Gold Open Access...for the low, low price of $2950. (The free default is a somewhat less accessible variant of OA.) Somewhere out there, I'm sure there are universities willing to provide subventions for that kind of investment. Mine, however, shows no signs of being one of them, and I somehow doubt that most academics in the humanities are wallowing in this type of dough. (Let's not even get started on adjuncts, many of whom are earning less than this per class.) The class ramifications here strike me as fascinating, in a grim sort of way: only elite universities can afford to provide subventions to cover gold OA publications for all of their professors, let alone some of them; in all likelihood, only tenured or tt faculty at elite universities can scrape up the cash out of their own pockets (and, given that many of those folks now carry significant student loan burdens, not even them); and 99% of adjuncts, meanwhile, are shut out entirely. Obviously, publishing this way is currently an option, not a requirement, but one does wonder.
