I don't see this as an issue. Sure, there are expensive stuff that get advertised which poor people are shy to spend money on. But there are lots of stuff that poor people do buy. Like toothpaste, mobile phones, shoes, clothes, dishwashers, deodrant, soft drinks. Although these stuff are cheap, they are billion dollar industries. And manikng a lot of people switch from one toothpaste to another will make a company a lot of money.
