The Borg has sown the seeds of its own destruction in multiple ways. I agree with the other posters who think that they will disintigrate over time.
First, the education ban means that any young ones who decide to stay in the Borg, will have to work many hours at low salaries just to maintain a poverty line standard of living. That means they won't be able to substantially contribute to the Borg either financially or with their time. That will lead to negative growth. Also, generally speaking, less educated people are not likely to attract more educated people to the Borg, which means that converts are not likely to be any better contributors than the home-grown variety.
Second (I have brought this up on a few other threads), there was a time (in the run up to 1975, during the 50s, 60s, and even the early 70s) when the writing in the Borg's publications actually bordered on scholarly. They encouraged the R&F to do outside research to confirm what the publications were saying. They encouraged studying the original Greek text of the Bible and also encouraged comparing other Bible translations with the NWT of the Bible. I believe the Borg's writers, having the appearance of being serious scholars of the Bible, were responsible for attracting educated, smart people to the Borg. When I was a kid (1960s) almost all of the elders were educated, dynamic speakers and leaders. That is all gone now. There are still a few smart, eloquent speakers, but by and large the quality has precipitously declined. There has been a significant brain drain as many talented and smart servants have 'seen through' the dumbing down of the message and left the Borg.
Third, those old timers and their children (from the 50s, 60s, & 70s), who are still in, are the backbone of the Borg. Prior to my exit in 1997, I had heard many old timers lament that they never expected to see the the end of the 20th Century in the old system. I suspect that the Borg's burial of the once-significant 1914 and their convoluted new teaching about the "generation," has many of those old timers harboring secret doubts about this being the last days. The "abundant proof" that the Borg offers for this time being the last days is nothing more than wishful thinking. The arguments they put forth are circular and full of logical fallacies. Even marginally thinking people intuitively sense this, although they may not admit it. The year 2014 may make many of them sit up say WTF and that may lead to a wholesale exodus.
Fourth, the R&F old timers may already be starting to doubt the GB's authority and its self-proclaimed role as channel for God's new light. Just below the facade of a happy organization there is probably a critical mass of simmering malcontents who just have not identified themselves to one another. IMHO, there may be some catalyst that starts people talking and that may trigger a mass exodus.
Fifth, the Borg's policies and tactics are taking them in the "Kool-Aid" (and I mean that literally) direction. This is something I never thought I would see (call me naive). Some of the members are bound to come to their senses and bail.
In any event, it will be interesting to see how things unfold over the next several years.
Cheers,
