Read "The Psychology of Influence" along with some of the stuff by, e.g, Kahneman and/or Tversky on behavioral economics and the various cognitive biases humans have that lead them to make poor decisions. I assure you that corporations have read all of this and are taking advantage of it to part you from your money, selling you products that they make you think will increase your happiness. Another resource on this would be Robert Shiller's book "Phishing for Phools, The Economics of Manipulation and Deception".
This isn't about taking personal responsibility. Even when you become fully aware of the insidious way in which our culture works, it's impossible to entirely avoid being taken advantage of by marketing and advertising. We humans are made to think in certain ways, our brains have evolved in a way that gave us cognitive biases we can't escape, even when we're aware of them. Being aware can motivate us to change the culture itself (and its laws), though, so in the future people are less affected by corporate deceit and greed. Yes, this would likely mean lower corporate profits. (Question how we're conditioned to think of lower corporate profits as a bad thing.)
