After living 5 years a small town with almost no ads beside local events and the like, I almost want to puck when I come back to a big city and get crushed by ads all over the place.

As mention, 99% of ads are for useless shit that people never need in the first place, including a lot of ads for consumer credit (to buy TV, cars and shits).

Once we realize that's removing these are in citizen best interest, we will have made a massive step forward as an advanced civilization.
