I think MLM is different. A small number of people might make a lot of money, funded by the losses of most of the rest. In that respect its more like gambling, and people can be more easily fooled to think that they'll be one of the lucky few.

Working as a driver for uber/lyft isn't really like that at all. You know approximately how much you can stand to make per hour. There isn't a small pool of drivers somehow making tons of money at the expense of the rest. Being a driver isn't predicated on mistakenly calculating your odds of winning big.
