Not a poem, just a quote from a song called "The Tower" from the band "Vulture Industries", which I love, and that I think somehow describes the way we live nowadays as a satire.

Rule number 1:
Each man is what he owns
Whether or not one truly exists is a question of having things
Rule number 2:
Things have purpose while the only purpose of flesh is to possess them
Rule number 3:
What one does not possess it is mandatory to land
Rule number 4:
The bond is the marrow of your bones
Rule number 5:
Debt is inherent and the birthright of the young
