Originally the words of the Wizard of Oz.
Now often used as a catchphrase that describes an organization or policy that attempts to conceal its true intent.
Example:
In the United States, colleges have joined together to create an unelected, "quasi-official" group of people called the NCAA to "govern" college athletic programs.
These schools and the NCAA gross millions of dollars each year, while denying any cash to the athletes, who are "amateurs." The NCAA's "stated purpose" is to make sure student athletes get scholarships.
Pay no attention...to the millions the schools and the NCAA make from CBS, ESPN, etc.
