From a Washington Post column by Helaine Olen headlined “This all-but-forgotten con man sold America on ‘fake it till you make it'”:

Glenn W. Turner is now all but forgotten. But this salesman extraordinaire in flashy suits was once all but omnipresent in American life. Turner, the son of a sharecropper, told people they could all be rich and successful like him — if, that is, they made an investment in his multi-level marketing company. They would peddle “mink oil” makeup and his “Dare to Be Great” motivational tapes, and they would collect more money by recruiting others and taking a percentage on their sales.
