One of three things are going to happen:
1. They're going to experience significant growth, a la 1975. The money will be rolling in again, and the GB will be set for another few decades.
2. They're going to bottom out and belly-up. There will still be a handful of faithful followers, but I can see the MAJORITY of them leaving in disgust.
3. Or the U.S. economy crashes, things start to go even more haywire in the world, and it may SEEM as if the end is REALLY close... and right then and there is when the GB will require all faithful servants to drink the Kool-Aid. After they drink the Kool-Aid... the world will turn around and mend itself and things will go on as before. The only people gone will be all the faithful JW's who drank the Kool-Aid, thus the world will see another tragic ending for a cult.
The last possibility is what really scares me...
