What fast-food chain does Schlosser primarily use as an example throughout the book?

In "Fast Food Nation," Eric Schlosser prominently uses McDonald's as a key example to illustrate the broader themes of the fast-food industry. McDonald's is not only a representative figure of the fast-food culture but also serves as a symbol of globalization, marketing strategies, and societal implications associated with fast food. Schlosser delves into how McDonald's success has influenced industry standards, labor practices, and agricultural practices, showcasing the impact of the fast-food pipeline on American society and beyond. The chain’s practices and its role in shaping consumer behavior provide a critical lens through which Schlosser critiques the fast-food system as a whole.
