In terms of being taken advantage of, I feel that there are areas outside of product ads that really are of greater importance. Politics is an important example where information, misinformation, and manipulation run rampant. Teaching kids to recognise influences and to introspect on intentions is essential if social and self awareness are to be sought. Understanding ads is like the training wheels of understanding social manipulation -- the penalties of misunderstanding are relatively small, but they do add up until the money adds down.
