I'd agree with Moxy. The current GB are products of the cult, immersed in it's brainwashing for decades. No doubt they really do believe they are God's channel on Earth.
It's a delusion. But the forces maintaining the delusion in their minds are the hunger for power and riches, like any other deluded megalomaniacs.
They control people, and this makes them feel good. But they see nothing wrong in this, since it is "God's Organization" they are at the helm of, so therefore it must be the correct thing to do.
They amass huge fortunes in "God's Organization", which they have effective control over. But it's God's money, that they happen to be in charge of, so that's OK too.
The delusion is to warp their base motivations into the divine purpose. That's why you don't see them craving attention. True power is silent and invisible. They know this: often they will impute it to Satan, how he has fooled the world into not believing in his existence so that he can manipulate them all the easier. They cannot quite go that far, yet the more out of the spotlight they stay, the less critical attention focused upon them, the easier it is for them to ensnare yet more people.
Their supposed humility shows that they know the mechanisms of wielding power over others all too well.
As for money, they have effective control of billions. All of their living and travelling expenses are paid for. That adds up to a considerable amount in hidden benefits above the monthly allowance.
Just my opinion, of course.
