Most people here report that the Society's main focus in accumulating money. Like Deepthroat, I say follow the money. I just don't understand how they make substantial money. The books are offered at low cost. JWs are generally poorly educated so they don't have millionaires and billionaires to fund the work. Their overhead is lower than business paying a fair salary to their workers.
I also believe that most Witnesses are not venal. If they were interested in money and other worldly things, it would have interfered with their recruitment in the first place. Do the Witnesses publish any financial information? I do note that for a group that criticizes offertories in church and the highly polished silverplates, the Witnesses push harder for money than any church I've ever attended. Stewardship in churches generally lasts a few weeks at most. Tithing churches may be different. I visited a fundamentalist church and before they said "Good Morning," I was shepherded to a special room where a financial planner was available for me to tithe on my first visit.
Thanks for my enlightenment concerning this.
