They can work if you are good at convincing other people that it can work, and then they sell the idea to other people and then those people do the same, and so on so on so forth. It is more about getting other people beneath you than about selling the products. The more people you recruit and the more those people recruit and so on so on so forth the more money you make, and you become an annoying SOB by trying to recruit everyone that you know. In the meantime the products cost way more than they should because everyone up that pyramid gets a cut of the profit from everything everyone they recruited sells and everyone those people recruited and so on so on so forth. There wasn't that annoying.
"Before you criticize someone, walk a mile in their shoes. That way, you'll be a mile from them, and you'll have their shoes."
