Earlier quoted context omitted.
Mormons tend run the companies and seed the initial demand. Moms with built in communities are big markets. Wherever you have a big military, police/fire/prison presence you'll see these all over. Also certain church communities, certain freelancer type industries, (yoga contractors, photographers) etc.
I've noticed that "military, police/fire/prison" families and some church communities like to "support our own" and buy from "locally owned businesses". I think MLMs allow people to buy what they think is a locally owned business that they believe will return dividends to their own community. Sadly the dividends that MLMs return are mostly negative (debt, friction of social bonds, etc).
If you go to a police or fire station and ask, easily 30% of the wives are nurses, as it’s a job with super flexible schedules. MLM gets pitched as a way to make some extra dollars.
