Well I hate to disagree with y'all but I don't think it's about the money so much as the power. After all, 1 billion US dollars is not that big a deal for a global organisation with 90 odd branch offices. I really think that the reported turnover is a natural consequence of owning a lot of valuable property in NY and other places, plus the contributions of a bunch of "borg drones".
I grant you that my experience is limited, I only served in a branch office in a little backwater like NZ for 5 years, but what I did see was men with a lust for power and control rather than lust for money.
And to be fair, I have seen some of that money used in some rather altruistic ways. The South Pacific region has some fierce weather form time-to-time and many 'dubs living in the Pacific Islands have had their homes destroyed by flood, hurrcanes etc. The WTS has donated money to help them rebuild several times.
Please don't get me wrong, I'm not trying to defent the WTS, I hate the barstards, but I'm trying to say that I don't think the prime motivation of the WTS is money, it's power and control.
