Raworth says we need to rethink economics from the ground up. Instead of chasing endless GDP growth, she proposes a new goal: helping everyone meet life’s basic needs without causing further damage to the plant. Her ‘doughnut’ model shows a safe space for humanity, between a social foundation (like food, health and education) and an ecological ceiling (like climate stability and clean air). Raworth challenges old ideas like the ‘rational economic man’ and market equilibrium, arguing that people are social and economies are complex systems. She calls for economies that are designed to be fair, distributive and sustainable, and urges us to stop treating growth as the only measure of success.
