What was one of the main themes of Upton Sinclair's novel "The Jungle"?

One of the main themes of Upton Sinclair's novel "The Jungle" is the need for government regulations to protect consumers from corporate greed. Sinclair wrote the novel in the early 20th century to expose the harsh conditions and exploitative practices in the meatpacking industry. Through his vivid depictions of the working and living conditions of immigrant laborers, he highlights the dangers posed by unregulated industries, such as unsafe working conditions, unsanitary food production, and the overall disregard for the well-being of workers and consumers.

Sinclair's purpose was to raise awareness about these issues, leading to public outcry and eventually prompting regulatory reforms, including the Meat Inspection Act of 1906. The novel serves as a critique of capitalism and the impact it can have on people's lives when profit is prioritized over ethical standards and consumer safety. This context reinforces the importance of government intervention to safeguard public health and welfare, making the theme of regulatory need prominent throughout the narrative.
