In the minority, I know, but I think it quite possible the whole thing could collapse. JW theology does not allow for a weakening religion that is decreasing in membership. According to JW theology, there is supposed to be an increase in the end and a great shout of warning to the world. As JWdom grows weaker, it looks more and more wrong.
I view it kind of like the physiology of a lot creatures. There is a situation called "homeostasis" that is characterized by all body systems' working properly and working together in harmony. When one system starts to function improperly, it affects other systems. If the situation is not corrected, the whole overall system with its various feedback loops can get to a point of no return at which point the body crashes and death occurs.
I think JWdom is sort of like that. For example, lower attendance at meetings hurts the morale, spirit, and zeal of those in attendance. As they get weaker, some of them stop attending. That makes the situation even worse. In the meantime, donations dwindle, the preaching work weakens, etc. All of these phenomena are interconnected and feed back to each other. I believe there could be a crash and that JWdom can't exist as a small group as some say it could.
Things change. Look at how shopping has changed in the last few years (at least in the U.S.) I see a lot of brick and mortar retail businesses dying and at the same time, I see huge distribution centers being built all along interstate highways.
JWdom's time is up. The heydey is over. It is in survival mode. It is no longer proactive; it is simply reactive. It is flapping at the water trying to keep from drowning. Whether it crashes or just simply continues to weaken remains to be seen, but I hope for the crash and think it's possible.
Businesses and other organizations do crash.
