Exposing the dark sides of MLM-Mormon and now MLM-FLDS culture in one quote:

If church members want to be financially successful, they’ll need to overcome their suspicion of outsiders, said Harvey Dockstader Jr., a veteran network marketer who is a member of a polygamist group in Centennial Park and owns a health food store in neighboring Colorado City.

Network marketing, he said, is a great training ground for people with a history in the FLDS Church. “It teaches how to be social, how to deal with their bottled-up fears. From that perspective, it’s therapeutic. They may not make money, but they’ll blossom if they participate.”
