What is a culture that has writing and where people do many different types of jobs?

One example of a culture with a developed writing system and diverse job roles is ancient Mesopotamia, often referred to as the "cradle of civilization." The Sumerians, who inhabited this region, created cuneiform writing around 3500 BCE, which was used for record-keeping, literature, and administration. Mesopotamia had a complex economy that included agriculture, trade, craftsmanship, and various professions, such as scribes, merchants, and artisans, reflecting a rich tapestry of social roles and economic activities.
