Well, people only have power over others to the extent that the others allow it...
Unfortunately, JWs are trained and indoctrinated to give power er deference to those with position and titles. Some JWs, esp those outside of NY or newer pubs, have never even heard of Bethel Elders. But among those who do know who and what they are, they are given extra props. They are perceived as having just a little bit more holy spirit and just a bit more blessing...esp since they are elders at J's house...Bethel.
Some pubs back at the home congregation fawn more over a returning/visiting bethelite than their own local elder. So imagine...a Bethel elder. True, they arent on the Branch Committee, but its all relative.
