Even before the COVID-19 pandemic in 2020, capitalism was stuck. It had no answers to a host of problems, including disease, inequality, the digital divide and, perhaps most blatantly, the environmental crisis. Taking her inspiration from the 'moonshot' programmes which successfully co-ordinated public and private sectors on a massive scale, Mariana Mazzucato calls for the same level of boldness and experimentation to be applied to the biggest problems of our time. We must, she argues, rethink the capacities and role of government within the economy and society, and above all recover a sense of public purpose. 'Mission Economy', whose ideas are already being adopted around the world, offers a way out of our impasse to a more optimistic future.
