The whole premise of MLM is that a few will make tons of money off the many. It is designed to work against the average person. If it were really so easy to make money from it, then everyone who signed up for an MLM company would be rolling in cash. The reality is that most people never make any real money from it. The scheme is to get as many contacts out of the person before they throw in the towel.
I was involved in ACN for about 4 years. I worked hard. I went to every weekly, monthly and quarterly training session. I sponsored people into the business and got down a few levels. My monthly residual check even got close to $100. I made some bonuses but I figure I spent about 4 times as much as I made.
The people who make it big have shark personalities and they make it big by feeding off the rest of us.
