As someone who was at Bethel, albeit many years ago, I can attest to the fact that the vast majority of us had no special insight into the workings and machinations of the GB. In fact, I had a friend who worked in the Service Department and he didn't seem to have any special information to share. If he did, he didn't share it. Basically we were all drones, doing the bidding of our overseers. At the time there was an Orwellian sense that one was being watched and evaluated at all times.
I always thought it kind of strange how Bethel males were looked up to by the rank and file "publishers". Some of my Bethel acqaintences were so perverted and neurotic that I wouldn't have introduced them to my own sisters, yet Witness mothers wanted their daughters to latch onto them. If you were an average pioneer with no special skills, and applied to go to Bethel, you got accepted. I think the pioneer requirement was dropped later on. In my case, a more courageous choice than going to Bethel would have been to join the military and possibly go to Vietnam or work in a V.A. hospital as a conscientious objector. Instead, I chose the bullshit option.
