Recent developments make me think they might be. The problems they are facing are not just lack of funds but also draining authority, and the two could be a heady and explosive mix.
One of the best analyses ever written of the Watchtower was a book called "Trumpet of Prophecy" by sociologist James Beckford in the 1970s. I don't have the references but Beckford noted an important aspect of Watchtower ideology: whatever problems occurred at a local congregation level, ordinary members always envisaged such problems as local aberrations. The top of the organisation was viewed with utmost respect, even sanctity. Any injustices that ordinary Witnesses faced were conceived as a result of evil among local low-level representatives. The leaders of the organisation were kept in the highest esteem. They were like the imaginary friend who was always on your side. If an elder treated you bad, you just knew that the GB would disapprove of them, if only they knew the details of the situation. When the magazines said, "wait on Jehovah" it felt like they were saying: "we know many local elders are bad, but unfortunately you have to put up with them for now, the GB is on your side".
It's hard now for ordinary JWs to maintain the delusion that the GB are exemplary or that they're on your side as an ordinary JW. In fact I'd say it's near breaking point. Which feeds into lower donations, which causes the GB to behave more erratically and lose further authority, which in turn feeds into yet lower donations. It's a vicious downward spiral.
The early tremors of the earthquake, looking back, might be instances like when Jaracz brushed aside the Panorama reporter: "we don't answer questions". One pioneer said to me on the ministry the next day: "I don't like that man". Then there was cancelling the book study. Didn't the GB realise that for ordinary JWs this was socially the most important meeting? And giving the false gas price explanation too. Don't think people didn't notice. And then there was the September 2007 KM that put a stop to organised independent Bible study. Then the branches started closing in places like Austria and Swizerland that had had branches for over a century.
Then came the real shocks to the system. The number of anointed started going up fast. Not only that but no good explanations were offered. Then a series of wacky explanations of the generation, each weirder than the last, until the ultimate overlapping absurdity was settled upon. More branch closures, cut backs, layoffs, begging for money. The GB broadcasts with their weird mannerisms, gold watches, pinky rings, tight pant talks, begging for money. And begging for more. And showing off charts with overlapping Franz. And more begging. And more closures. And confiscating money from congregations. And promising more building. And then announcing building to stop. And then printing a calendar of building projects when building projects have been abandoned. And mishandling abuse cases, and disastrous appearances of GB member at the Royal Commision, and disastrous media coverage. And more begging, and more confiscation of congregation funds, and more cut backs, and lay offs...
Ordinary JWs no longer revere the GB. They no longer imagine they are on their side. The GB have become a bunch of weirdos who keep harassing them for more money. Leaders who claim God's backing but have to keep cutting back the organisation. And when they don't get enough money just from asking, they confiscate it from congregations. And tell congregations they can't spend their own money as they see fit.
They don't just face money problems. There has been a serious ideological breech in the JW organisation. Which feeds into lower donations, increases the GB's panic, produces more cutbacks and weird behaviour, more loss of authority, and so on and so on. If they don't get a grip soon I think they face the biggest crisis of their history. The combination of lack of funds and dwindling authority could be their downfall.
