"Passive income" as your only financial salvation is one of those memes that broke off from the MLM "tool scam" industry, that is, selling courses, seminars, and other training materials to people in MLMs on the pretext of teaching them sales, marketing, and business, but it's really just brainwash material designed to keep them from leaving. The other big one is positive thinking/the law of attraction/"The Secret". If MLM is the kaiju, these are the spider-things that fell off the Cloverfield Monster's body and started killing people in the subway tunnels. But like how Robert Smith performed with Siouxsie Sioux as "The Glove" while still fronting The Cure, these memes have built plenty of side scams while still enjoying friendly partnership with MLM itself.
