If revenues for Brooklyn Bethel per year alone are equivalent to 951 million dollars, then this is about 158.5 per witness(given six million witnesses).
There's more money than that coming in worldwide, because of the OTHER Bethels in the world.
So, where does the money come from? I think that should be checked into...or my maths should be checked into.
Either way, some reassurance is necessary here, because the figures look odd to me, given that most of the witnesses I've known aren't putting anywhere near that into the congregation coffers per year.
