People have a misconception of advertising as a noble or worthy, and necessary thing. In business school it’s taught that it’s purpose is to inform rational consumers about what to buy. Actually if you look at advertisements, you learn it’s purpose is to misinform irrational consumers into buying. Advertisements have learned to use emotional messages, sex, repetition and other irrational means to sell.

Quite. If a person needs a thing they will realise that themselves and go out and buy one. Advertising is 100% about things you don't need and have no real reason to purchase.
