My family fell for lots of them.
Nova's General Store, a mail-order grocery pyramid scheme that my mom and aunt fell for.
Cleopatra's Secret, Culture Farms -- Milk mold farming. My parents lucked out with this one. I talked them out of reinvesting the $8000 they got after investing $4000. The pyramid collapsed a week later and our friends that my folks suckered in lost $$$ on the deal.
Amway -- My brother.
Combined Insurance -- My brother. This was a very cult-like business with intensive indoctrination classes and high control door-to-door sales. They dropped you off in a neighborhood. They picked you up. You couldn't use your own car. Long hours. Little pay.
Sports Cards Trading -- Both of my brothers and my father invested heavily in this.
Savings Bond pyramid scheme. My Mom and grandfather fell for this one. You buy a savings bond in the name of the person at the top of the chain letter and mail it to them. When it matures they have boocou bucks! You have nothing but a sense of patriotic pride in bolstering the economy. "It isn't a pyramid scheme because you aren't sending money through the mail!" Yeah, Mom, right! Her denial to justify her participation is unreal. Kind of like the denial you need to be a JW.
BTW, I called them pyramid schemes, but my Mom always emphasized it was multi-level marketing or bubble sales. Same thing as pyramid, just called something different. Denial again.
My cousin got involved in one of the most lucrative schemes. My family claimed it was legal, which may be true, but was it ethical? You decide. I made my mind up long ago that I wanted no part of it. He made a deal with a local charity that he would donated x hundred dollars a year for use of their name. Then he opened a second hand store under their name. Caring people would donate all the merchandise, he sold it, paid the operating expenses, and gave the charity their x hundred dollars per year. The rest of it was his. I think there were tax loopholes too because this was for a charity. It all fell apart when my stupid uncle (my cousin gave his dad a cushy job there) kept trying to witness to some of the employees and they brought a religious discrimination/harassment suit against my cousin. I keep expecting this same scheme to show up as a storyline on the Sopranos someday.
