people will seemingly hop aboard anything that gives them authority over other people. i am reminded of that scientology grade chart that leaked a while back[1]. the end result of each training was usually the ability to give the training to others. so while all orgs obviously want to remain on a positive tipping point with the general membership rising to serve hierarchical functions over time, scientology teachings seem to exist mainly an opportunity to advance relative to other scientology members.
