That specific example seems sorta yikes opinion for somebody with hiring power. Aren't people who get targeted by MLMs victims? More importantly, what does that say about how hard they work? Or being a mom?
It‘s a stereotype for the sake of a stereotype. I don‘t think anyone identifies with such a narrow unrealistic stereotype, so there is no point in arguing for an entirely hypothetical marginalized group.
By the way, hiring is all about judging people‘s past work, and I‘m sorry to pop your bubble if you think past MLM work or having large gaps in your employment history doesn‘t reflect bad on anyone.
