Of course they benefit. It doesn't have to be sitting in a bank account with their name on it. They travel well, eat well, dress well, good health care, all expenses paid, etc. What more could they want?
I truly cannot see this being the motive to make more wealth. They have plenty of dough to take joy rides, eat well and such without needing to make the millions they make and are making.
They certainly need lawsuit money to win or payoff legal encounters. Money also talk.......the one thing the Watchtower need. With their godawful history, they need all the financial help they can get for present and future problems.
Another thing, I doubt the GB has a lot of input on how to make financial gain. They leave this in the hands of Lawyers and investors with different brain power than they have.
And lastly....perhaps....just perhaps, there are truly some who really do it for spiritual intrests, but I highly suspect these ones are a minority and over-ruled by those with dollar signs in their eyes who's hobby and satisfaction is making money for the corporation and getting patted on the back for doing so.
