Benjamin Hale offers a great point of view to consider when looking at our political choices--and many non-political choices for that matter. It's really a great article.
The veil of opulence assumes that the playing field is level, that all gains are fairly gotten, that there is no cosmic adversity. In doing so, it is partial to the fortunate — for fortune here is entirely earned or deserved. The veil of ignorance, on the other hand, introduces the possibility that one might fall on hard luck or that one is not born into luck. It never once closes out the possibility that that same person might take steps to overcome that bad luck. In this respect, it is not partial to the fortunate but impartial to all. Some will win by merit, some will win by lottery. Others will lose by laziness, while still others will lose because the world has thrown them some unfathomably awful disease or some catastrophically terrible car accident. It is an illusion of prosperity to believe that each of us deserves everything we get.
