It's pretty clear the WBTS has cash flow problems. I suspect there is a good portion of JW's who feel trapped in the borg due to family ties. It's likely they have stopped contributing in a material way to the organization.
The sale of high value Brooklyn real estate may be enough to keep the wolf from the door for a while. When that particular gravy train has ended do you think the GB will ever attempt to impose tithing on the r&f? How do you think the average witness would respond?
