yeah the coolest thing about modern economic systems is that we can culturally recognize the ethically barren landscape of pyramid schemes as a bad thing that we obviously don't get into and even ban in sane places! But economically well yeah sometimes your friend since high school is just going to bumble into an MLM scheme, financially wreck themselves, bomb their social lives, and spew propaganda about being their own boss selling soaps, and that's just ok. that's fine. if anything, it's their fault for falling for it!
