Well I think it is safe to say that when push comes to shove and they need money the Governing Body will start selling these buildings. Now maybe this new pledgeing money on a regular monthly basis and robbing the congregation's of their bank accounts that are higher than three month running cost might forestall the sale of kingdom halls in the immediate future probably or most likely.
But when the going get tuff they will be selling them right out from under the publishers who paid for them. This will be tramatic to many when this occures, any way word will spread no matter how much they try to stop it. So how will the Governing Body decide which halls to sell first? Will they get a big map and throw darts and the closest kingdom hall to the dart goes on the auction block? How will they make this decision there are so many KHs probably thousands which ones do you choose?
Well I'm thinking the Kingdom halls with the lowest donations for the WT Corporation get chosen first, they don't want to upset the high rollers but those poor congregations that yeild small returns piss them off first make them travel 50 miles to get to a meeting why care if they stop going at all because they ain't contributing it also may serve to make some Congregations start uping their pledge amount once they see the patern(low contribtion to the WT your Hall goes up for sale) and put 2 and 2 together.
