Great question.....at least in the more industrialized world it seems that the cashflow from the publishing business has all but dried up, they still have the 'publishers' purchase the literature that they are going to 'place', but not nearly as lucrative as it had been.
At present it appears that they are mainly dealing in real estate, and selling off assets in Brooklyn and either relocating to areas with lower costs or just not rebuilding since the need is not there for the publishing volume and like the rest of the corporate world, they are 'right sizing' there free labor, because even though there is a low cost for the labor, there is still a cost and a liability.
This is merely my opinion, but I think the next move will be an attempt to further isolate themselves as 'special' and therefore further cutting off the 'worldly' people. If they can succeed at blasting the needs of the world, they may be able to better get into the wallets of the followers, better appeals for the worldwide work. They may also succeed by having the local congos build more KHs but then turning around and consolidating and selling.....
The thought of a 'place of safety' is interesting, I think they may be attempting to do this somewhat virtually, by further isolating themselves from the worldlys, and if fully isolated, what is the true need for being materialistic.
