David K. Shipler's book, "The Working Poor: Invisible in America," highlights the plight of low-wage workers who, despite their crucial role in supporting the economy, often find themselves in precarious economic situations. These individuals work tirelessly yet remain at the margins of survival, constantly battling to maintain their livelihoods without falling into poverty.

Shipler argues that society neglects to recognize the essential contributions of these workers, treating their struggles as separate from the overall prosperity of the nation. He calls for a shift in perspective, urging us to acknowledge and address the systemic issues affecting the working poor, as their well-being is fundamentally tied to the health of the entire economy.
