“For example, regions in the Americas that were well suited to cash crops that required intensive farming and benefited from large pools of labour became places with high levels of inequality and limited distribution of rights among the population. Locations better suited to less intensive forms of agricultural production on the other hand - regions that favoured the growing of wheat, for example - proved to be more egalitarian, with better distribution of rights among the population. The short explanation for this is that crops that required lower labour input produced smaller profits and therefore meant there was less to fight over, and more reason to co-operate. This is one of the reasons why it is possible to identify a strong relationship between a country's socio-economic development and its distance from the equator.” HistoryInequality Book:The Earth Transformed: An Untold History Source: The Earth Transformed: An Untold History
