There is a scheme. Once the money is donated, it becomes property of the WT (or it becomes holy) and nobody is allowed to use for anything. BoEs have no authority on that money. Since some time now, they request and push all congregations to transfer whatever they have in their hand to Bethel.
From my personal experience, there was a brother, had to be operated, but had not enough money and family coverage to get the operation. BoE decided to use the congregation's money for that urgent need, help the brother, but some of the elders' conscience "pricked them" and the next morning they called Bethel whether this decision was theocratically correct or not. Bethel replied, no you can't use the congregation's money and if you want to help the brother, 1. find his relatives 2. ask for private donations. Once the money is contributed, it is no longer touchable.
Congregations, innocently thinking all their donations are going to Bethel and used efficiently to help brothers/sisters in need worldwide.... I'm certain that when they say, they are helping and have helped XX thousand brothers/sisters financially, these must be the Bethel workers and special pioneers' monthly salaries.... Deception at work.
