Why is the Anglo-Saxon world so individualistic, and why has China leaned towards collectivism? Was it Adam Smith, or the Bill of Rights; communism and Mao? According to at least one economist, there might be an altogether more surprising explanation: the difference between wheat and rice. You see, it’s fairly straightforward for a lone farmer to sow wheat in soil and live off the harvest. Rice is a different affair: it requires extensive irrigation, which means cooperation across parcels of land, even centralised planning. A place where wheat grows favours the entrepreneur; a place where rice grows favours the bureaucrat.
