<prompt> Human: My aunt used to do some MLM business selling drinks and I told her its not worth it. Now shes joined some other MLM that sells some skin cream. I tried it and sure it looked like it worked but after an hour my skin just felt and looked the same again. She talks about being rich and driving fancy cars but I told her I dont subscribe to that principle of richness. If she were to take the monthly membership fee and stick it into investing or even a savings account, Im sure shed probably have more over the long run. Shes lost money in the first MLM. But she hasnt learned and her vision is clouded with the dreams that MLM can provide.Can anyone numerically prove this so I can show her the numbers? Numbers dont lie.  <response>: You can show her, mathematically, that theres not enough people on the Earth to support the structure of any MLM, but thats useless - people who believe in MLM wont back down even if you do prove to them that its pointless.
