Marketers are the new witch doctors. No one is immune - if you care one iota for anything you own or long for anything that can be purchased, A) Congrats, you're human, B) Marketing works on you.
Remember, advertising is the LAST step in marketing, the first if figuring out who you're selling to and then designing a product to appeal to them, then packaging and promoting it.
Example: marketing people make Volts and Prius', not environmentalists.
