Just to point out that Primerica is part of Citigroup, i.e. Travelers Insurance, Travelers Bank, Solomon Smith Barney, Citibank, etc. and has over $1 trillion dollars in assets. Not exactly a fly-by-night business.
I have knowledge of family members that have invested in these criminal activiites and lost their shirts, their friends and even some members of their families have become alienated.
Most, if not all of these MLM scammers are blatantly ripping off the public and nothing seems to be done to control them. A large, local MLM outfit is bringing in millions a month is sales of health supplements to innocent "distributors" but those in the downlines are eating dirt and going broke. Avoid these pyramid traps like you would a case of AIDS!
