First, sorry for the "pout" in my previous response. It was supposed to be "point" but the spelling corrector disagreed. I get the "relative well-being" argument, but honestly it doesn't change my mind. It seems to be an argument that puts jealousy in front of objective improvements. Extrapolating again, this is the dispute between those who think inequality is a problem in itself and those who think that as long as poverty is reduced, inequality doesn't matter. I would be fine with a system that doesn't allow exchange as long as the situation described in the article wasn't allowed to happen (i.e. if there's a spot for me in my first preference, I won't be allocated to my second one). I'll try to find time to read your references, thanks!
