I see it as part of a general dumbing-down scheme. Drop the quality so much, that only non-thinking puppets in a vegetable state, completely stripped off of all their mental capabilities, remain there. It reminds me of the scene in Matrix, with the vast 'crops' of human 'batteries'.
Keep them in a vegetable state, extract their money. Simple as that.
For how long? Maybe for longer than we'd wish. Religions and cults are stronger than a rational man would wish, anyway. Maybe we should focus on enjoying our (not eternal) lives instead of waiting for something that will probably not come during our lifetimes (i.e. the "End" of the WTS)
