Now that the 'anointed' are getting either too elderly to be promoted or judged insane for saying they are anointed cuz they're too young,....pickings are getting slim. 'The best,' of the anointed men who would become the GB, are no longer so good. You have men dying on a desert island. The last ones to become the leaders are not going to be as good as the first ones who were natural leaders.
Also I was thinking, what does it take these days to be a true believer fundamentalist witness? Back when GB 1.0 was being educated, evolution was barely taught in school. GB 2.0 would have been much more exposed to it, and for a true believer witness to survive, it takes a lot of shutting down the mind and a more rigid personality. These guys have always followed the rules to a t, to be promoted. Some of the nice elders all of us have known were probably doubters, more merciful, less legalistic. That's not the type of elders these guys are. They have been dogmatically rigid their whole lives and have chosen to be ignorant and purposely devalued education because it is a threat to their fundamentalist faith.
