As I keep saying every publishing company is doing what the WT is doing...the cost of ink, paper, printing facilities now is far higher than it has ever been and therefore the WT are simply cutting costs.
Warwick was to cost $200 million when it was being planned...they sell the NY property for $1 billion. They cut a lot of costs already and will continue to do so until they are the point they can live with what is coming in.
I think SBF's opening post is very good but still can't see them demise because of money issues...they will address these at some point.
But they are on a gradual decline and in 20 years+ will have major issues...not money perse but doctrines...but again I expect them to change that too.
Religion is a lot like a sports team...no matter how poor your sports team is you stick with them...ditto for a religion.
Slow long decline yes...but they won't go bust because of a lack of money...they will evolve and adapt to survive that IMO.
1914 and the anointed/overlapping generation will be huge hurdles to overcome.
