"It can be a shock to find out capitalism has not always existed. Economists present 'the market' as the natural state of humanity... When you realize that capitalism, once did not exist---either as an economy or a value system---a more shocking thought arises: it might not last for ever. If so, we have to get our heads around the concept of transitions, asking: what constitutes an economic system and how does one give way to another?"
