Economy and politics are presented as two great powers through which the entire System is rocked, including its content and meaning.
The swing here is a metaphor for finding some kind of balance amidst the imbalance of the constant movement of opposing elements. An attempt to describe the reality of time.
Primary issues such as freedom, education, food, work, etc. reveal the reality that is, next to what it could be. It is about capturing the harmony between elements in discord, as a way to make contradictions coexist.
