This New York Times opinion piece by Nicholas Kristof examines the devastating impact of recent U.S. foreign aid cuts, spotlighting how millions of vulnerable children around the world—especially in Africa—are losing access to life-saving food, medicine, and basic support. It echoes the findings of the landmark ‘Worms’ study by Edward Miguel, Michael Kremer, and others, which showed how low-cost health interventions like deworming can dramatically improve long-term outcomes for children. As funding dries up, the global consequences could be profound—making this a crucial moment to reflect on what decades of research tell us about the power of aid.
