Oxford academic Kate Raworth in her 2017 book 'Doughnut Economics' argues that out present economic system is not only creating a more unequal society but is destroying our planet at the same time. It is in that sense 'not fit for purpose' and is failing the society it is supposed to serve. In seeking an alternative she questions our present goal of ever-increasing economic growth and advocates what she describes as "doughnut economics". The inner ring of the 'doughnut' stands for the level of social provision below which no one should fall, the outer ring stands for the limits we should set to those activities which damage the planet. We will examine Raworth's book to assess how far her analysis is accurate and, if so, how far her solutions could work in practice.
