Final answer:
The paradox of social injustice from the poem 'From the Dark Tower' is 'The Reversal of Fortune,' which shows that those in power can eventually become subordinate to those they consider inferior.
Step-by-step explanation:
The paradox of social injustice (contradiction) from the poem 'From the Dark Tower' that shows those who today enjoy power and prosperity may one day become subordinate to those they deem inferior is called 'The Reversal of Fortune.' This paradox highlights the idea that social positions and power dynamics can change over time, and those who are currently privileged can fall from their positions of power. The poem challenges the notion of inherent superiority and emphasizes the fluidity of social hierarchies.
