Should you replace a meritocracy with an egalitarian society? A meritocracy is rule by the best. An egalitarian society is one where all people are considered equal. In the real world that makes sense, but the people of MfD are *not* equal. Ninja are stronger, faster, and tougher than civilians as well as being able to break physics with finger twitches. They also tend to be better educated. Clan ninja are another (albeit smaller) step above clanless ninja -- clan ninja have access to education, techniques, and resources that clanless ninja do not. There are even two clans whose bloodlines and clan lore make them smarter than everyone else...or, at least, better at problem solving, which is pretty similar. Why shouldn't they be in charge?
