The WTBTS is rich, no doubt. Reason why whenever they say at the assemblies that there's some sort of deficit, I do not contribute one more red cent than what's reasonable.
Same for KH contributions. I calculate # of publishers and monthly expenses, then contribute just enough to cover the bills if all pubs contributed the same amount.
They'll start practicing what the scriptures teach in terms of greed and being content with having basic needs covered.
