what exactly do you mean by that? If the test is “I made some money” then yes, some people do make money in an MLM – very very few make a boatload, a few make some serious dosh and a few make peanuts. The vast majority of people LOSE MONEY.
So if the criterion is “money gets into someones hands” then MLM works just like robbing banks “works” – some people do get away with it but at the expense of a lot of other people.
MLM is inefficient, it is probably the most inefficient way to distribute any sort of product and it functions by adding layer upon layer of expense.
What is “working” about that???
