It seems like you're just saying that because you don't like them.

The ad industry is not full of idiots, it's got an impressive amount of technology and data behind it proving the ROI on every side.

You have not uncovered some kind of mass conspiracy. I'd strongly recommend you either talk to people in the industry or read up on the technology and results available.

I'm not postulating a conspiracy. I'm only pointing out the resource-wasting zero-sum game which drives most of the advertising. I'm not denying that ads have effect. Of course they have. But what matters is marginal effect, which generally stays constant, because there is only so many things one can buy, and so many attention one can spare.

Also, I worked alongside people in ad industry and I'm very happy I escaped it. I've seen how things are done and I'm not pleased. I don't think ad industry is full of idiots - it's not the smarts I am disputing, it's the morals.

For a good illustration of some of the points you make - when tobacco advertising was banned in the UK, profits went up markedly because demand remained the same and there was no longer the massive outlay.
