Our politicians are hung up on keeping the growth curve rising. But does GDP really tell us all we need to know about a country's wealth and well-being? In this new RSA Short, Kate Raworth makes a powerful argument to look beyond economic growth alone for a true measure of prosperity and progress. Kate Raworth is a renegade economist teaching at Oxford University, and is focused on the rewriting of economics to make it a fit tool for addressing the 21st century's social and ecological challenges.
