No, the GB don't 'live it up' in the style of some televangelists, or even in the style of Judge Rutherford (who would have made a great modern TV preacher), but there is a tremendous amount of money being funneled into the Organization over the last few years
(Brooklyn property sales, required amounts being donated every month by congregations, congregation bank accounts being drained by headquarters, pleas for donations to support a KH building program that never happens, and accepting credit card donations that Watchtower used to ridicule Churches for.)
How many billions have they raked in over the last 5 years? It is unprecedented in the Society's history.
Couple this with all the financial cut-backs.
(Magazines are almost nothing now, no new books released ever, missionary program cut, special pioneer program cut, District Overseers cut, Bethel workers being sent home, Bethel services such as waiter and laundry are cut, no new KHs being built, and more that I can't remember as I write this).
Some say law suits are taking it, but they only amount to a few 10s of millions of dollars, which is a drop in the bucket compared to the multi-billion dollar windfall currently taking place.
Where on earth is it all the money going.
