The quote "Being poor is a full-time job" from David K. Shipler's book, "The Working Poor: Invisible in America," emphasizes the immense effort and struggle that an individual faces while living in poverty. It highlights that surviving on a low income requires constant vigilance and work, including finding employment, managing limited resources, and navigating social services. The relentless effort can often consume the time and energy that might otherwise be spent on personal growth or family development.

This idea reflects the broader systemic issues that contribute to the cycle of poverty in America. Shipler's work reveals how the working poor often lack opportunities for advancement and face significant challenges that hinder their ability to escape their circumstances. The book sheds light on the hidden struggles of those who work hard yet remain invisible, illustrating that poverty is not just about a lack of income but also about the constant fight for better living conditions and dignity.
