I remember my local high school's motto when I was growing up was something like, "we're not here to teach, we're here to create good, informed consumers".

Never mind the obvious problems with that statement, but just considering it on face-value: how can people become good, informed consumers without having some kind of exposure to the concepts of how easily information can be collected about and used to manipulate people?

I don't expect most high school students to inculcate the full breadth of the topic, just as so few seem to actually learn and retain anything about history, social studies, or even the freaking alphabet (I've met way too many people who think the English alphabet has 25 letters). But currently, the general populace has no idea the extent to which they and their data can be manipulated. It would be enough if all they learned was "you and your data can be manipulated".
