Like, if you sell a luxury handbag. When people buy it, they know 70% of the value comes from the advertising saying "this is a high value product" as a status signal. I think that's really dumb, but that's what people want.
It also existed a long time before ads itself did.
So, you are aware that advertising is in large part responsible for shaping what is perceived as high-value status signals in society. You're also aware that for certain products the only distinction between those and their alternatives is that specific high-value association.
How come you started out from the position that advertising is "just showing off different aspects of the product" then?
If an ad convinces you to, say, get a gym membership or go on Ozempic, who's to say what happens next? Maybe you do start feeling better about yourself.
Advertising is a horrific industry. It probably always was, but at the modern scales, it's outright dystopic. I think there's simply a large amount of cognitive dissonance around this issue because advertising drives the paychecks of a whole lot of people, and it's rather difficult to get a man to understand something when his salary depends upon his not understanding it.

"You'll be happier if you purchase this thing"
"You're not good enough as you are now, but you will be if you purchase this thing"
"Other people you admire or respect have purchased this thing, and if you do too you'll be more like them"
"Other people will like you more if you purchase this thing"
"You'll be more attractive if you purchase this thing"
"This thing will be worth more in the future so if you purchase this thing it will make you money"
"This is your only chance to purchase this thing, so if you don't it now you'll miss out on this price"
I don't think any of them has to do with how awesome "the thing" itself is. Obviously there's more to, say, an expensive watch, than its ability to tell time
