I agree about the bunker mindset.
It is an organization centered around the belief of the immanent end of the world and continual increase until then.
It wasn't supposed to go past 1914, 1925, 1975, the generation that saw 1914, the end of the 20th century...Even after that, I believe the GB thought Armageddon was the ultimate solution to any 'short term' problems: legacy costs, child abuse lawsuits, any mounting debts.
Growth began to stagnate in the mid-90's...I believe there will never again be a heydey of recruitment as it existed from the 60's to the 90's. Now it's a matter of member retention and yet the members are part of the segment of society that is least educated, and therefore, contributions are not on the increase.
I do wonder if people vote with their wallet before they vote with their feet. There is a captive audience (awake JWs), and there are those who believe in it somewhat but are worn down or aphetic as well.
