Of the scientologists I know it is a system of self improvement classes.
Personal Responsibility, health, motivation....you'll find a bunch of businessmen and I'd say a largely successful healthy group of people.
While it has its bizarre side many benefit physcially, spritually and financialy from their association.
Sure, and the same thing could be said of Amway.
I was an Amway network marketer two decades ago for about a year and a half. I believe that I benefitted from their self-improvement concepts, and their energetic rallies. (Like Scientology, all of Amway's self-improvement concepts were taken from established psychological sources.) I felt more motivated and self-responsible. My sense of life was brighter and more optimistic. I felt like I could achieve anything. I had spent more money on Amway than I had made back, but I'm willing to consider that fair payment for what I had gained.
However, I'm happy I left Amway when I did. For all the positives, Amway has (IMO) a way of stealing your soul. It is very easy to become lost as a self-determining individual in all that self-improvement. The object (made quite clear by Dexter Yager and other high-level marketers) is to become an obedient clone of the ideal Amway marketer, and not your own freewilled person. Yes, you might become fantastically wealthy and successful -- but you would be a bird in a cage of gold.
This is the hidden trap. If you are offered something immensely good, you might not realize that there is a terrible price to pay somewhere down the line.
The Scientologist side says they are disgruntled employees. Listening to the reporteres and employees I'd say maybe, but a lot occurred. But also knowing some of these corporatate boot camps I'll bet many feathers get ruffled. Now it sounds like things went overboard, but how exagerated I don't know.
My overall opinion is the upstart is on its demise, its starpower won't find enough tread to last the next hundred years.
