I really don't think that the WTS is in any real danger of going broke in the short term.
I agree with the sentiments that this is all about rapid organisation change to protect against future shortfall and risks. These risks may include changes to tax status, compensation claims, reduced investment income, rising construction costs etc.
What is clear to me is that the decision making has absolutely nothing to do with spiritual goals. It is completely driven by bean counters. I really get the impression that the GB have let their hubris get the better of them and run amok with this plan and that plan over the past couple of years then some underling has pulled their bollocks out of their arse and given them some plain and simple shocking facts, coupled with some compelling strategies for rapid and persistent cost cutting.
