With the recent breakout of news about Len Clements, I did some looking and it appears that Mr. Clements, who is an MLM advocate, doesn't appear to earn his the majority of his living from MLM. Mr. Clements is free to correct me if I'm in error, but it seems like the leaders and biggest proponents of MLM do not make their living off MLM income, but from selling advice or training to MLM hopefuls. (ergo the old saying that you live with the classes if you sell to the masses).
Even the leaders of the big MLM's such and Herbalife or Amway, apparently make significant incomes not exclusively from Herbalife and Amway, but from selling training materials and conventions. It is my understanding that Robert Kiyosaki was a struggling author until his rich dad books started getting pimped by Amway leaders. All of a sudden he's a best selling author an a (pseudo) financial guru. Many who attended Kiyosaki's seminars have said it's a scam to sell you another more expensive seminar and not much of actual substance of taught.
Is it really a honorable profession to milk MLM hopefuls when their realistic likelihood of success is maybe 1% at best?
