The number of hours per recruit really does highlight how
incredibly ineffective the publishing work is ... but it doesn't cost
them (the org) anything (vs buying a super-bowl ad).
I don't think the quick ingathering of individuals before the end comes is a true concern to them. They must realize that if they were to purchase advertising on national television, they'd be overwhelmed with responses, overnight and the "Good news would be preached throughout the earth" and the long awaited end would come.
The problem is, the eyes of the public would be upon them. They'd be in the spotlight and would be accountable for everything they say and do and have said and done. There would be public scrutiny. The way things are now, they fly under the radar of the general public. Most people think their experience with JW's is an isolated incident unique unto themselves or their particular local. They don't realize the scope of what is going on. It's easy for them to dismiss them as just another fanatical religious group.
I think for the leaders at Bethel and for many JW's being a Jehovah's Witness is a way of life rather than a means to and end.
