Is there any way that these 300-500 vote holders get kick backs or monetary rewards that come from profits annually?
According to the charter, and to fall in line with the requirements for non-profit organizations, they cannot receive monetary gain from profits of that organization.
But...maybe they have something to do with, not the profits, but the expenses of the organization.
I sure would be interested to know how many of them own shares or stock in paper mills, and construction companies that the WTS does business with. Or how many are in the real estate business. And let's not forget about all the money to be made in the blood industry.
Who are these 300-500 men and where do they make their money from...or their relatives?
Back in the day that Russell was the grand poobah, the Society men were invested in businesses and industries that benefited from the WTS' existence (and so did Russell - he hid his assets so Maria couldn't get them in their divorce proceedings). It was Woodworth, I believe, who owned a transport business, and Russell was invested in paper companies and the subsidiary offshoots such as turpentine and kaolin* interests.
*kaolin is a type of white clay used in paper manufacturing and turpentine is a by-product of paper manufacturing
