Your list is right on target Vanderhoven. Why?
Because WTC studied the organizational structure of the Catholics and gradually began to emulate it. This started around the time that they joined the UN as an NGO. They wanted to gain insight into the Catholic structure in particular so that they could manage funding, growth, assets, control and all the other aspects of running a large multi-national religious organization. The Vatican had the playbook.
Without giving too much away, WTC implemented changes in the 90's that would help them "get organized". Their ship was in such disarray that some feared it would sink, and it came close a few times when policy changed, donations failed to keep up with expenses, spending veered out of control, etc.
Still, WTC chases the business model of the Catholics. Even now, they are employing the same legal guns that the Vatican uses. They know that dioceses went bankrupt, but they still believe in the Catholic business model and will follow it doggedly. What other choice do they have? Afetr all, it's not about religion - it's about business.
