Query: Very comprehensive and informative

I have just taken both marketing and public relations courses and this doc was both informative and actually entertaining because it breaks down the smoke and mirrors around one of the most pervasive forces in our American culture...the hyper-consumerism fueled by marketing. It also discusses the emotional basis of purchasing decisions and how consumers turn their back on reason when it comes to many purchasing decisions.
