No evidence of financial problems? Watchtower has lost its core business of selling books and magazines. What more evidence do you need? Do you think it can run on thin air?
Your evidence that Watchtower is not in financial trouble is that they are "still there". But any organisation facing collapse is "still there" until it actually collapses. What sort of evidence is that? And besides it's about 25% less "still there" (by some measures such as bethelites and branches) than it was a couple of years ago (probably more than 25% in terms of declining print output) and shrinking rapidly. The question is can it shrink to a sustainable level, or will it shrink away entirely.
The point is to look for indications of what's going on. If cutting quarter of your staff in a single year is not an indication then what on Earth would be? Or cutting more than a quarter of your branches? Or failing to actually produce a physical product at your annual conventions - for the first time in your 140 year existence. If these are not indications (among many other things!) then what on Earth would be?
And again with the 1 or 2 billion from property sales. We have been through that. Yes it must have helped, but how much? How much did Warwick cost? And how many years can the rest cover the deficit? At their level of spending (quarter of a billion on full time servants outside bethel alone, every year) perhaps not very long!
Even if Stephen Lett and Samuel Herd hadn't said a word, observers would obviously have been speculating about their financial situation anyway, given these developments. Their announcements and the panicked look on their faces just confirms what we already know.
