As I said, there is no reason to believe that women and/or minorities would be inherently better. But in large enough numbers, with varying enough backgrounds, things might be different for a while.
As a starting place I think a woman who made her living as, oh, a barmaid, is going to have a perspective closer to mine than someone whose "Pup" bought his way into Harvard and left him millions. Might not be anything wrong with that millionaire, but we keep saying we want a change, right?
