I wish I could fund an as campaign to free people from the perception that ads are to sell you products

Ads are there to change your behavior to make you more likely to buy products, e.g., put downward pressure on your self esteem to make you feel "less than" unless you live a lifestyle that happens to involve buying X product

They are not made in your best interest, they are adverserial psycho-tech that have a side effect of building a economic and political profile on you for whoever needs to know what messaging might resonate with you
