The GB are merely figureheads. When it was announced that magazine printing will be transferred from Wallkill to Canada, it was said that the GB approved that. What does the GB know or care about where magazines are printed? When I asked Witnesses that they said that the GB was the FDS and the printery was part of the master's belonging so they were appointed over it. But the fact is that the factory overseers make the decisions and then the president of the WTBTS approves it and the GB rubber stamps it.
As to who runs the org: The captalization on the belief that it matters to God what people do and they must do things 'just so' makes it easy for people to come along and then to assume the position of the ones capitalizing. 'Hey there are gullible people out there who will do anything to save themselves, to see their dead loved ones, etc.' People are so tied to the adherance to a deity, they will do anything for that.
