Well the media is pretty intense, but being in a cult, wow, the assault on your cognitive ability is relentless.
I would always wonder "Why do we need so many books?" now I get it. I was never one for reading all of them though I figured if it was important we would study it eventually. LOL
If the believers wanted the normal things bad enough they would pursue them. That's the sad truth also. It is easier and less painful to stay.
Maybe it's also a fear of failure to avoid taking any real risks in life. Let's face it the definition of success in the org is pretty easy just show up and do what you're told.
