Perfect summary!As I see it, the abuses are built right into the organization's structure and policies. Given that one must follow Hubbard's policies without deviation, I don't see any good every coming from the church. (micro)Managing by statistics, draconian ethics, rpf, money-money-money policies, and the built-in fraud of no-results mean that the organization will always be abusive.
In addition, the hierarchy command structure, which was designed to protect Hubbard from everything, ensure no one ever questioned Hubbard and guaranteed absolute obedience to Hubbard ensured that a psychopath would always do anything to be at the top. Anyone decent near the top didn't have a chance and never would.
