Yesterday I ordered a used book from Amazon, and remembering the static shocks in that Mother Jones article (btw, wearing a metal thimble to touch the shelves with seems like it would fix those shocks), I was faced with a moral dilemma. But how was I to solve it. Pick one of the higher priced used book options? How do I know they aren't using the same distribution warehouse and just pocketing the difference. Without a "doesn't treat workers like crap" seal of approval, I don't see what I could have done. I'd love to subscribe to a white-list/black-list of sellers on Amazon for various ethical measures but it isn't there.
