This documentary questioned modern consumer culture and the standards of modern society. It discusses about how people are becoming over-cumbered with things to compensate for happiness.
An example shown in the documentary was of a business man who was conflicted when working his way up a corporate ladder. Upon reaching his promotion he realised that getting a raise wasn't as amazing as society makes it out the be. The difference of his promotional raise and his increased tax levelled out. Unsatisfied by his work vs his financial payoff he talked about how success is often shown through what you posses and not how you feel.
This documentary made me question what I own for satisfaction and what I own for the sake of owning it. In my spare time I chose to go through some of my belongings I had no emotional attachment to and clear them. This was a good self reflecting experience and encouraged me to be cautious of what I want to buy for the sake of buying.
