I have never understood why anyone would want to be an Elder.
It's because Elders are put on a pedestal, admittedly a small one, but they are elevated above the R&F. How many times you hear a prayer in behalf of the CO, DO, GB, Elders, Pioneers, etc? Ever hear a prayer for the lowly publisher? NOT. Not often anyway. So it's nice to make it to the "inner circle". This is held out as a goal from the time born-ins are little boys.
Second, most who have such aspirations enjoy the politics of it all. They all want to be a Shaker n Mover -- they all aspire to getting assembly assignments etc. Soon they realize that if they are not rubbing elbows with the right Heavys in the circuit, it ain't gonna happen. Some play the politics better than others. The ones who can't play the game end up sitting on the sidelines.
I think some stay because they think that they can do more for change "from within" than on the "outside". Personally, I'm Doubtful Of Change happening.
