Scientology is a simple, classic pyramid scheme.
You pay money to advance in the hierarchy, after which you charge those beneath you for advancement.
At the bottom of the pyramid are book sales and a pathetic herd of ego-annihilated cultists.
"Getting Chicks To Say Yes: L. Ron Answers the Booty Call"
"Hey, If It's In a Bestseller, It MUST Be True!" "Travolta 3:16"
"Making Your Own E-meter With Dixie Cups And Duct Tape"
"Chapter 26: In Which Luke Discovers that L. Ron Vader is His Real Father"
"Chapter 5: Rush Limbaugh Is A Big Fat Idiot"
"'Old Mother' Hubbard -- L. Ron, the Transvestite Years"
"Chapter 12: Geez, You're Still Buying This, Aren't You?"
"The Human Mind: That Vast Realm Half an Inch Behind the Forehead (Two Inches Back for Scott Hamilton)"
"When a Lawsuit Hits Your Eye, Like a Big Pizza Pie, That's Scientology"
"He's NOT the Telescope Guy!"
"Chapter 11 - How To File For It"
"Movie Stars -- Are They Gullible, or What?"
"Chapter 3: Post This on the Internet and We'll Sue Your Ass!"
and the Number 1 Least Known Chapter in "Dianetics"...
"Commandment Number One: 'Show Me the Money!'"
....also read that this cult is slowly but gradually taking over a lot of production theaters/studios and buying up a lot of the Viacom stock...ergo...Travolta has been able to "buy" a script into a movie produced by the Scientology in order to make a living....
