> I like philosopher John Rawls' conception of a "Veil of Ignorance." Rawls would ask: would you rather live in a society with, say, 1% billionaires and everyone else in poverty, or one more evenly distributed around a middle class -- without knowing in advance where you would end up in this society? The answer may well depend on one's level of risk tolerance, but I'd wager that most people wold opt for the latter.
Except that that's not the choice that we're faced with.
Instead, we're faced with "lots of billionaires, a huge middle class, and poor people with 2 cars and 4 TVs" vs "nasty, brutish, and short". Oh, and the former gets better over time much faster than the latter. If you're really going to be serious about the ignorance thing, you should be ignorant of when you live.
