I would disagree on this. The reason is that the main point of most ads is to induce artificial demand. When successful this is essentially making people think their lives are missing something, repeatedly. I think it is fairly self evident that at scale this simply leads to social discontent, materialism, and the overall degradation of a society.

There are endless studies, such as this [1] demonstrating a significant inverse relationship between ads and happiness. The more ads, the less happy people are. And I think it's very easy to see the causal relationship there. And this would apply even if the ad industry wasn't so scummy.
