I checked out Herbalife, and there were plenty of meetings there, too. You were supposed to go from door to door offering vitamins (I wonder what they are going to do this January 1, 2010 when Codex Alimentarius goes into full effect in the US). They gave you the lines they wanted you to use to present the products. What they didn't tell you is that the product is about as good as what you can get at a drug store, or maybe a bit better.
Also, they boasted that you could make all sorts of money. Most of that was recruiting new members, not selling vitamins. In theory, that looked very promising--and I investigated it thoroughly. They didn't tell you that the average person working 60 or 70 hours a week (and not dogging it) can realistically expect to make around $1000-1,500 a month. This is very similar to what the witlesses are told about field circus--that they could expect all kinds of new recruits, but chances are you will get very few.
And yes, Herbalife breaks the law (and not the new Codex Alimentarius law, either). There are two offenses. The catalog gives no indication of the product size, and it is the law (a fair law, at that) that the customer has the right to know how much of a product the money buys before buying it. Second, when I tried to set it up, it asked you for the sales tax rate in your state. The tax is supposed to be based on where the customer lives, not the vendor. If I, for instance, live in New York and sell to California, that sale is based on California, not New York, sales tax. If I make another sale to Texas, that sale collects Texas tax and not New York. Plus, some products are taxable and others are not in many states.
Hey, at least with Herbalife, all I lost was money. They didn't try to tell me how to live my personal life (aside that I was supposed to identify myself as an Herbalife distributor). They also don't ask me to protect pedophiles--I believe a tax offense and not disclosing the proper net weight of a product is better than coercing children into being molested and then silencing them.
