We should strive to lie less period! Not only the poor are lied to, the middle class is the main target IMHO

Like access to health care?

False advertising is already illegal.

Other than that, there's nothing wrong with creating desire for something. It's ultimately up to the people to make their own choices.

Blatantly false advertising is illegal. There's a lot of room between "blatantly false" and "valuable and informative". That's why we have upvote and downvote mechanisms.

Also, I understand not everyone believes this, but I think there is something morally wrong with the form and scale of manipulation that modern advertisement brings.
