Elizabeth Warren, a former Harvard Law School professor and currently a Democratic senator from Massachusetts, published This Fight Is Our Fight in 2017 in the run-up to her eventual announcement that she is running in the presidential campaign of 2020. This book is intended to explain the major principles of her platform and tell her readers about her background.

Warren uses her own story to show how the American economy has changed to the detriment of the middle class. She writes in many points of the book about her family's story. After her father had a heart attack, her mother was able to support the family with a minimum wage job answering phones at Sears. Though her family was by no means rich, they were able to pay their mortgage and pay for food. She writes that she was the beneficiary of government programs, such as funding for education, that benefited her. She contrasts her story with that of current working families who cannot get by, even when they work hard. For example, she writes about Gina, who works at Walmart but still cannot pay for her needs. Warren also writes about college students who are plunged into debt. The broken middle class is one of Warren's motifs. In addition to featuring stories about the working poor and middle class, she also includes easily digestible statistics in bullet points about the way the middle class has been harmed in our current economy.

Warren also uses examples of the profligacy of the rich to show the way in which the economy has been tilted to help the rich instead of the poor. For example, she writes about parties on Wall Street in which firms hired the musical group Maroon 5 and paid them $500,000 to perform. Her intent in using these types of stories is to contrast the wastefulness and excess of the way the rich are able to live with the suffering of the working poor and the struggling middle class.
