ADCMS -
Yes they do not have faith in the morality of their own members. I tend to share your viewpoint on this and other matters. One thing however, if the homeowner was a good person, and they put it all togehter, would they ever REALLY donate to anything other than the WWW? I mean, do you know JW's who have given money to charities run by secular organizations or (gulp), religious institutions?
I think no matter what money would go back to the branch. I didn't realize much of the building material was donated by other groups. I wonder if they knew it only went to JW's or if they even cared.
Its amazing how the branch will "take advantage of Satans system of things" whenever they get the chance.
