Dystopian literature is often used to write about wars, politics, and social structures. A dystopia is a place where everything goes terribly wrong and used in literature it is a genre of fictional writing used to expose a bad scenario and talk about poverty or oppression. In this description of the 1900s, the writer uses dystopian literature first by exposing the possibility of a perfect world, with no poverty, no wars, social equality, and technological advances, leading the reader to feel hope only to crash that hope in the final sentences in which the writer explains how none of this happened and how it only resulted on times of violence, poverty, war, and discrimination. "However, throughout the 1900s, no matter how much humanity progressed, perfection was never achieved. The promises of technology and sociopolitical theory only resulted in war, poverty, famine, and chaos" (Ostergaard, Commonlit).
