Actually, it's been my experience that for the most part the decent elders have been 'removed' - or left from frustration. It's tough to remain a good apple in a barrel full of rotten ones. You either get out, conform to the rest of the power hungry, or at the very least sit quietly and take your lumps anytime you dare to cross the 'elite' 'glorious ones' ...
One of my points is that since I have observed the opposite of what you have observed, than we are all working with segmented views of what the entire elder body is like. Therefore we should refrain from demonizing them.
