Have you got any evidence that Watchtower has made money from their blood policy or literacy programme?
In my view Watchtower is in the worst position of any church of its size, and most churches of other sizes for that matter. Historically they relied on book sales and now they are selling off their assets to keep afloat. (Not to mention lawsuits, aging dependents, declining members in rich countries, increasing members in poor countries, and so on) What they will do when the money runs out is not clear. It seems that in their complacency they thought Armageddon would come before the money runs out.
