I fully agree with that post. MANY MLMs are ways to separate members from their money. MHA is a prime example of it since there was no business model to it at al other than the downline. Others, like Tupperware, Mary Kay, Avon, and I think Shaklee have a legitimate business which is marketed using MLM which is a system which works and has stood the test of time. When new ones pop up they need to pass a test of having a legitimate sellable product which can be the core business of it members.
Again, I do not condone and have never done MLM and think it is not for most people, but it can work for the right person with the right attitude towards it.
Selling a semi legitimate product at insane markups, using predatory multi level marketing technics is still despicable.
Regardless, the definition of a MLM company is made by analyzing how they make their money. A normal legitimate business makes money by selling a product or service at a premium.
A MLM makes their money by selling the right to "buy in" to be "allowed" to market their "products" . - It makes absolutely no difference whether the product is legitimate or not. It generally is not, and/ or is massively overpriced. This is because the product is not subject to normal market forces.
The MLM push of harrasing desperate people to "buy in", " subscribe" or wtvr is the scam. It is wrong.
