Wants are much different than needs, though it would seem that various groups do a very good job of convincing individuals that they need all types of consumer goods. This rather insightful documentary from American RadioWorks looks into the world of buying and selling by talking with marketers, scientists, designers, and others. Produced by Chris Julin, Ochen Kaylan, and Ellen Guettler, the documentary explores topics such as the science behind shopping and the quest to market products directly to teenagers. Visitors can listen to the entire program here, read the transcript, take the "spendthrift-tightwad survey", and also view photographs of the American shopping experience. Additionally, visitors can take a look at their very thorough set of external links and resources on this subject.
