I had a similar experience. Unfortunately a good friend of mine is suckered in, and wanted/wants me to join too. He actually showed me how much he spends on buying their crap products and how much he earns from it. On average he spends 3 to 5 times the amount he gets back, and it takes months before he gets a payout back. So completely brainwashed into thinking it's a good deal, even though he is spending thousands more than the average consumer, and relies on overpriced inferior products.
Would have considered joining myself, until I realized there isn't a single product in their line I would consider consuming. Nothing in the entire product line is something I would ever consider buying. Even the stuff I do buy outside their business that they offer (like fresh produce), he talks me out of it because it doesn't offer enough return into the pyramid. Too many controlling contradictions.
Amway, Worldwide Dream Builders, and Legal Shield are all popular systems. Watch out for the promises they make. None of the promises they make is based on the hours you work, only the commission results made from getting others to sign up and buy a business licence through them.
