I know very little about the GB and their habits. I do know that JWdom has changed drastically since I left. The GB are moving to the country and seem to be spending a lot on amenities that are not available to the rank and file. Instead of being grateful to the rank and file for their free ride, they just keep asking for more and more money - quite a change!
Similarly, U.S. Congresspeople are also in the pockets of those with plenty of money to share with them.
I don't believe the GB live the opulent lifestyle of a Joel Osteen or Jimmy Swaggart, but they do seem more out of touch with the real world than JW leaders of the past and don't seem to care about the suffering of sexually molested children in the interest of protecting their "reputation" and image.
