Indeed, advertisement is nothing else than misinforming people at their own expense. It is a scourge of society.
The marketing budgets is part of "production cost" and in the end is paid by all consumers, like a tax you cannot avoid.
For this taxation, we receive false information and are encouraged to act (mostly) against our own interests.
I'd rather just pay for stuff, honestly and up front, instead of this hidden cost that you almost cannot avoid.
Marketing is mostly a non-productive distraction for society as a whole, that brings nothing good.
Drugs, for example, are also a non-productive distraction, but at least provide the consumer some pleasure (hopefully).
But advertisements, only lead to wrong pruchasing decisions and waste your time and money.
