Once again I have to defend MLM. I was in one starting in 1993, and we left the WTS in about '97. I got started to buy weight loss products at the wholesale prices, and boy did I lose weight, and fast. Everyone I knew noticed and wanted in. Some of them did very well too. I didn't do much with the business part of it unless people came to me, because I was too busy being a good JW, elder's wife, etc.
As soon as we started to withdraw from them, I got busy in the business, and because they were so similar, I really knew how to do it. I became very successful, with an international downline. Eventually, with the Asian financial crisis of the late 90's, I lost most of my Asian downline, that were making me a ton of money.
I set up a website to sell the products and got tired of the meetings and constant recruiting, so now I only sell off of my website, and do very well, with a regular income from that.
The products are personal care, health and nutritional supplements, and weight loss products. The FDA banned the ingredient that really worked for weight loss, so they don't work as well anymore. The other products are top notch though. We use many of them.
My point is, that some of the MLM business are very good, with excellent products. How well you do, depends on you. You can't just join and wait for the money to come in. Your upline isn't likely to build your business for you, although I've known a few who do that.
By the way, I was not in Amway. My company was Enrich International, that merged with Rexall Showcase in about 2002 and is now called Unicity International. I don't talk against Amway though. They were the first and broke the ground for the rest.
