The JW leaders are in it for the money. Let's face it, JW leaders live very simple lives compared to most religious leaders in the world. The corporation certainly need money to make their world go 'round, and have displayed greed in many cases that they well deserve to be called on, but anyone who asserts that the WTS leadership have money as their personal motivation overshoots the mark with a wide margin.
Its true, JanH, that the JW leaders do not consider the gathering of wealth in the same vein making as "normal" people might. They do not want to enrich themselves to show off ostentatiously by possessing opulent houses, cars, or to maintain a lavish lifestyle
However, the making of vast amounts of money is certainly a source of pride to them. The growth of the organization as a demonstration of their intelligence and leadership is equally important to them and they want to maintain the corporate status that they now enjoy. So while they may not be "in it for the money in ways that we can understand", the continual growth of the Watchtower Corporation/ with its accompanying wealth, is indeed important to them.
