Market America / SHOP.com

With its high startup cost, $500USD, plus required ongoing monthly product purchases, website fee, and seminars $200USD~, does this makes sense?? Why are there sooo many people so gullible enough to signup for this and pushing it through to their friends/families? Or am I missing something and it does make you good enough money for your efforts??

Any BlackHat-ers tried or is doing this?

Thanks!
