I think the whole organism is flawed and rotten, it was rotten in fact to its foundations right from the start. All egos and Dollar bills. As to the level which corruption penetrates I suggest that it is systemic although a majority of followers mean very well.
In the hierarchy there are the big people at the top enjoying the undeserved rewards of their scam with a layer of brain dead wannabes below them. All the rest including the elders are the little people with Watchtower induced lobotomies.
The whole con trick is based on a fictional story dressed up to look miraculous and the GB play on the credulity of the little people who have been lured into it by a ticket to paradise.
I don't think the org can remain an attractive option to outsiders for much longer. I do hope the heartless GB will be publicly outed-- but the true believers by their very nature will hang on to the bitter end whatever happens.
