In the period when human rights haven't been recognized, wealth and power will determine the fate and social status of the Egyptians people.
The social structure in ancient Egypt is similar to the Europeans during the middle age. Kings and Nobles are considered as a representative of God with divine right to rule the empire while the people have no power to do something that deviate from the rulers.
The only small chance that people can get to move up from their social status is through becoming a great military leader , becoming rich from trading with other empire, or marrying into the loyalty.
