If you think you are not being effected by advertising and go about buying what you "want" you are kidding yourself. We are ALL played like puppets and we ALL do things directly related to it.
EVERY SINGLE THING you pick up at the store is marketed to YOU to pick it up. From the shelf that particular item is on, to the direction you turn when you first walk in the store, to the color and size of the package to the music played in the store to the products it is shelved with to the items you pass going to it in the store to the price and on and on. Marketing is a science, a science that BILLIONS of dollars are spent on every year.
You ARE a product of that marketing. Just the fact that you think you are not effected is the proof that it works.
