Let me also note something less extreme. The good people at Nestle use to run an ‘ad’ campain in African countries to make mothers belive that natural breastmilk is dangerous and if they want their babies to survive they have to buy their product. They were given free samples which lasted roughly the lenght until the mother stopped lactating. Of course then the honourable people at nestle stopped providing the formula milk for free. It became rather expensive for the child to survive actually. Ah Nestle.
