The Watchtower organization has lots of old money in the form of massive assets, including huge cash reserves.
Lately it has concocted novel ways of multiplying its overall assets, including enormous amounts of new cash and new cash flow. In the real world we all live in, lots of capital makes a corporation stronger. Watchtower is becoming stronger financially.
Watchtower's leadership does not give one hoot about doctrine. It's new mode of strengthening itself is to alter how it rakes in financial assets. That's the new light! That's Watchtower's new religious movement.
