My partner will probably never financially recover from her time involved in a MLM. She was involved in one from well before we got together, and she has since escaped thankfully. I am extremely lucky to be in a position while I can reasonably support both of us so she can focus on the debt, but it's not going to be something she ever really pays off.
MLMs make me extremely pissed off, becaues they absolutely ruin lives. They should be illegal everywhere, but only very few countries actually have a blanket ban on them. China and Saudi Arabia are the only countries I know of offhand.
