Sorry everyone (this is a long reply, but it's something I feel passionate about), as someone whose family business is for a very reputable multi level marketing company, I have to say that unfortunately you are speaking from a position of ignorance.
We don't work for FL and I don't intend to say who we work for (or my husband, more specifically, but it's our business as a whole) as I don't come to MN to plug our business. The views expressed by the posters here are not that rare - however - multi level marketing is something completely different from pyramid schemes (which are illegal, by the way). Multi level marketing is a widely used method of compensation within various companies globally, it is thought by many economists to be the business model of the future as it is incredibly egalitarian in nature (anyone can do well in an MLM business) and cost efficient for the company itself. It is entirely legal, logical, highly regulated, and PROFITABLE. It is based on sales of tangible products, not signing up other people to do the work for you. Before anyone in an MLM business gets paid a penny of royalties or bonuses on other distributors in their downline, a whole host of stringent sales criteria has to be met by all parties involved. The so called 'passive income' of an MLM business is not easy to come by, but it can be completely life changing for people who stick with it.
As for the quality of the products, I can't speak for other companies, but what you will typically find is very high quality products because MLM companies can afford enormous research & development budgets (because independent distributors are effectively their sales force, freeing up enormous resources). Sometimes people say 'yes but all vitamin pills/shakes/whatever are the same, so why pay over the top for them' but that's a silly argument, that would be like saying all cars are the same, but no one could seriously claim that Vauxhall is the same as a Bentley and that it should cost the same, that it drives the same etc. Especially when it comes to health products, quality matters, hugely.
A lot of people who call MLM companies 'scam' are people who were looking for a"get rich quick scheme" and were then disappointed to find out that such a thing does not exist!!! Believe me I wish it did, but it doesn't, and MLM is certainly not it. It is not an easy industry to survive in, but if you find a way to thrive, then it gives you a measure of both financial freedom and lifestyle, that no other job I know of can offer.
It is all about working incredibly hard for a long time, and being ethical, professional and dedicated to your work.
It sounds like the problem here is that the lady in question is simply not acting professionally. No one wants to be harassed and harassment does not give any results, on the contrary, it makes people say 'it's a cult'. In our business, we would never harass anyone and in fact we make a point of only working with people (be it clients or distributors) who really want to work with us. It only makes sense. We have over 600 distributors in our downline and at any given time a minimum of 30 retail clients and I can promise you that not ONE of them ended up with us through harassment.
This lady possibly needs some better training, possibly she might be in the wrong job, it's hard to say. I don't know much about FL but they have been around for a long time so I'm assuming not all of their distributors can be doing such a poor job.
