First, people get offended when "others make money from others". For God's sake.... what the hell do you think happens when you go to work?? Is not someone paying someone for some service or product? That is business! For those who have their own businesses like myself, you understand that. If that did not take place somehow, in some way shape or form, then businesses would not be.
It's not the making money from selling product that is the problem with MLM. Some MLMs are different from others, but for most of them, it is the building of the pyramid that earns money. You make money by recruiting and getting residuals. But no matter how great a product is, it only has x percentage of market penetration. Everyone you recruit below you has less opportunity to find customers and sell to them than you do.
So you get these guys who have opened up a region or are very near the top of a pyramid who got in when market potential was great who are making the 6 figure/month salaries. And they're there at the meetings saying you can do it too. But the simple facts are that every person who joins has less opportunity than the guy above him (if they're in the same area). The more people who join, the better for the top of the pyramid, but the worse for the guys at the bottom. It's basic math. The numerator (total sales potential) gets divided by a bigger and bigger denominator (number of salespeople). Each one makes less.
Then you throw in monthly quotas, and other "incentives" where these lowly people on the bottom end up buying extra products themselves just go meet some requirement or stay active. Buying things they don't need and are marked up 3 times as high as you can find elsewhere so that the upline can get its cut. Sure the guys at the bottom can make money by busting their asses, but barring all that work, the only way to make money is having people working for you. Logic says that everyone can't have people working for them. So those people have to bust ass or lose money.
For these reasons, MLM is is often preying off the guys at the bottom of the pyramid. That's unethical.
The basics of MLM are similar. Though some companies pay differently and have different products. Some are better than others and some manage to make money without hurting others too much. With some, even the guys at the bottom can make money without trying too hard.
Many MLMs are very bad news though. Salespeople lie about their income to recruit. People buy product to meet goals and go in debt buying crap they don't need. People are dishonest about possibilities with friends to recruit them. People are sold more training as a fix for why they aren't making money (training which mostly consists of "believe in this MLM"). Sometimes friendships are based soley on people being part of an MLM. Sometimes families and friends are broken up when people feel like they've been suckered by the ones they trusted. In some ways, there are MLMs that are every bit as much of a cult as some religions.
There may be some good ones, but I haven't seen any without a catch.
Are JWs unique to MLM? I don't think so. I've heard of other religions getting involved in it. Churches being divided over it. The get-rich-quick mentality promoted by it can lure anyone.
I have a friend who seems to continually go for every MLM and get-rich-quick scheme he can find and never learns. He is more selective about MLMs now, being more selective about choosing products he believes in. To date, I believe he has lost much more money in it than he has made. Recently he was in Big Planet with their long-distance and after using their service for several months (though cheaper services were available), I asked him how much he made. I think he made less than 20 bucks in 6 months, but spent probably 10 times that much buying from them. Don't order that Rolls-Royce yet.
He always blames himself. Didn't put in enough time, didn't try hard enough, need more training, etc. His new one Cyberwize is getting a lot more of his attention. He just got about a $500 check for signing up his siblings in a different state. If he actually opens up new territory, this one might work for him. But by comparison to that $500 check, I estimate he's spent over $1000 paying for various membership packages, not to mention training. Then there was a conference in Vegas. He's contracting. He's worried about being renewed. Taking time off means he both loses pay and potentially sends a bad message to his employer. And then there's the expense of the trip. So he's wondering whether this will be so big he won't need to renew. His MLM mentor told him, get this: "If you don't go, I can guarantee you WILL need to find a new contract when this one expires". Does anybody see the bass-ackwards logic in that statement? That was the clincher for him. Without promising a thing if he DID go, she only predicted an outcome which was almost 100% guaranteed no matter what he did, if he didn't go. He went and still hasn't made any descent money and still has to worry about renewal. Anyway, he's probably a couple grand or more into this. Not to mention the $200-$300/month vitamin habit he now has. From a company that sells a growth hormone stimulator made from 191 amino acids. Excuse me? Did they also invent some 170 new amino acids too?
That's another thing about MLMs, lies. Sure they've been around for years. So has 3-card monty.
So what else about this friend? He used to be a JW too and I think was involved in MLM at that time. Since then, he's quit the JWs after being disfellowshipped and found a new religion, The Way Ministries.
He is a very intelligent guy, but always seems to think there is some conspiracy afoot to keep him down. That there's always some secret knowledge he can atain to combat these forces out to get him, and by using this knowledge, his life will be richer. Financially for him, MLMs hold some secret to untold wealth that he's going to tap into - eventually. Religiously, he found a religion that also has a lot of gee-whiz type things. Secrets that nobody else has figured out. It's like a cross between JWs and pentecostals. No trinity, but speaking in tongues and healing. They have identified x-number of "devil spirits" acting against people, each with their own specific specialities. They have pinpointed Jesus's birth to within something like 45 minutes (because astrology was once given to us by God and was used by God's people). (reminds me of predicting 1914)
For him, I think, he has to feel like he has that secret knowledge that the world doesn't know about. Not too different from JWs in a way.
Despite our common distaste for all the MLMs our friend gets into, my wife just got into 2 of them. Avon was one. It went great at first when she started and everybody gave her a sympathy order or 2. Then she got stuck with product. Each month, Avon would bill you for a bunch of their booklets, whether you wanted/needed them or not. Eventually, she was paying more for catalogs than she was making and quit.
She's doing another one where she does shows in-home. Her actual shows weren't quite as good as those she was told about or taken along on (taken to shows in rich neighborhoods, where sales are naturally higher). Now that she's gone through all the friends and family that she can convince to have a show, she's high-and-dry with nothing on the horizon.
There are no real get-rich-quick schemes. They're either scams or they work with lots of your own hard work.
