The scale of social change, can be gained from contemporary documents. An inventory of staff of the northern estates of Amun, Ostracon Gardiner 86 (20th Dynasty c.1189 B.C.E), records 8,760 farmers were each responsible for producing 200 sacks of barley for the temple. A number of cow herders, each in charge of 500 animals, were also employed, together with 13,080 goat herders, 22,530 bird keepers (each in charge of 34,230 birds), 3,920 donkey drivers (each with 870 animals), 13,227 mule drivers (each with 551 mules) and an unspecified number of fishermen. This administrative document demonstrates the intensive farming and herding activities of just one of Amun’s domains. 
A further point to make is that the food that was once free for the tent dwellers now has a price, their labour. The concept of an exit represents the reality of voting with one’s feet, or strike action, where the conditions have become intolerable and the solution is to leave. The 18th Century B.C.E. texts from Mari, highlight the tribal groups that owed allegiance to the king had once tried to emigrate from his control, and so this is not an unprecedented move. But this does raise another question, Is this conflict of an ethnic nature? Or is it a disagreement over conditions of service?
