"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?"
