AlanF,
Such ideas tickle the ears of the foolish, and empower the unethical over the foolish.
That's an astute observation, and causes me to wonder about leaders offering simple answers to complex societal problems. It's fairly easy understanding why the gullible falls for simple answers, but the ethics of giving simple answers is intriguing, when the one in control knows better.
For example, politicians get elected by hiring more police, knowing crime goes down when people have living-wage jobs, not necessarily more cops on the beat. Religious leaders offer life eternal, knowing they don't know, but saying the expected because it makes people feel better. Of course, there are stages of unethical behavior that goes beyond the above. Sects like the Watchtower travel to the ethical extreme by telling followers to believe the unbelievable while forcing their lunacy with the gun of shunning pointed to the follower's head. As you said, it's an organization of unethical people holding power over the foolish.
The foolish flock to the one offering simple societal or religious answers. The Tower will always have a pool of people to suck in, and forums like this are there for followers that awaken. (It's always interesting seeing how pissed new ones get when they realize what happened.)
