PLEASE HELP I WILL MARK BRAINLIST. The Sumerians built the world’s earliest high cultures. History generally looks at some Sumerian inventions––writing, the school system, irrigation, complex architecture––as positive. But with larger societies came some negative traits, too. Bureaucracy, taxes, and social stratification––including the invention of slavery––originated in Sumer as well. In your opinion, is it possible to build a complex civilization without social hierarchy? Explain your reasoning.

The term classless society refers to a society in which no one is born into a social class. Distinctions of wealth, income, education, culture, or social network might arise and would only be determined by individual experience and achievement in such a society.

Explanation:

A wealth of evidence indicates social hierarchies are endemic, innate, and most likely, evolved to support survival within a group-living context. ... Despite some cross-species variability, there is strong evidence that hierarchies arise out of necessity and their existence is beneficial to social groups.
