I think advertising has some good and necessary uses in alerting consumers to legitimate value propositions. It also can encourage people to do things that are not in their best interest, for example to drink either Pepsi or Coke, or to use tobacco products before their advertising was widely banned. So I would separate advertisements into good (new restaurant near you that you would like to know about) and bad (preying on human weaknesses). Which one is this kind of ad best suited for? > providing value to users will maximize revenues. I'm not so sure. The "chumbox" ads seem to be literally all bad, selling things with net negative utility. What are the socially valuable uses for this that are going to outcompete miracle pills and snake oil?
