I have often wondered similiarly to what Russell said in that 1879 WT posted by Frankiespeakin -
If Jehovah is backing the organization, then certainly he could easily provide funds for it. I mean it's almighty God we are talking about here. Even if they did insist on some sort of tithing or giving for the principal of it, it certainly shouldn't have to be sent to NY. The funds should just be used around the KH or used to help the truly needy.
NY should be flush with money from Jehovah's blessing.
