Yes it works, but are you or your friends willing to work? If they run it like a hobby and don't put in the hours and elbow grease it takes to run a business then they will fail. MLM has a very high turnover rate,
Most people think they only have to sign up a few people and sell them a bunch of products. In a perfect world maybe. But not typical. I'm with a company that has a few different products, I only concentrate on one product. The truth is, it's not a product. I donate meals to starving kids. The more kids I feed the more money I make. It's different than your normal mlm, but I love it. I get to help kids, make money, get huge tax write offs and I don't stalk up on a bunch of useless crap that I don't use anyway. I think it's one of the best systems I've ever seen. Just my 2 cents.
