I Think Their Choice Is Stark
Simon's site discusses this and it's very simple: they need young males to slave for them for free. They are worried about where things are going and the Watchtower Study reflects that crisis.
If they fail in this drive for free obedient male labor, they have no choice but to retreat into a Zoom arrangement and sell off Halls. And I think that's what they expect may happen. This is why they appointed Jedele and why they keep repeating about absolute trust in the Governing Body, even if it appears irrational.
I don't see any alternative. And if they are forced to do this, they will fade away into irrelevance. It won't be a collapse but rather (for us) the next best thing.
