I don't like to do the generational thing, but I imagine that one reason our Galtian Overlords are the extreme sociopaths they are has to do, in part, with the fact that they're a couple generations removed from any awareness of material deprivation. The Great Depression, WWII, and Korean and Vietnam wars didn't exactly impact everybody equally, but the devastation hit across class lines a bit more. As such things recede, and the portion of the population who are on their 3rd and 4th generation of relative wealth grows, it's likely that the giant asshole class is something we're going to have to learn to live with.
