If you look at enough income opportunities online you will find a lot that are no better than, "send $30 to the top name on the list and add your name to the bottom".
I still feel strongly that the only true chance to make money is if the program lasts a few years, and most of these won't.
By finding a company that responsibly follows the real MLM business model of offering a quality product at a fair price that competes with traditional companies in the same market, you do have a real chance.
However, it is only a chance. If you want to see the fruits of your labor you have to work at it. It's called Network Marketing because you have to network first and then market.
But it's no more complicated than telling my friends about seeing "Master and Commander" at the movies the other night. I thought it was a far under-rated show and enjoyed it very much. Exciting adventure on the high seas against enemy forces as well as nature itself. Terrific photography and special effects. Problem is, if you go see it I can promise you the theater you attend will NOT send me a check.
If I tell you about my ISP, they will.
