Final answer:
The three types of societies discussed in class in regards to equality are band societies, class systems, and stratification systems.
Step-by-step explanation:
The three types of societies discussed in class in regards to equality are band societies, class systems, and stratification systems.
Band societies, also known as gatherer-hunters, emphasize equality, cooperation, and sharing. Decision-making is based on discussion and consensus, and there are no formal positions of leadership.
Class systems, found in capitalist societies, involve social inequalities where some individuals exploit and oppress others to gain power and wealth.
Stratification systems can be closed or open. Closed systems, such as estate, slavery, and caste systems, have little social mobility, whereas open systems are based on achievement and allow movement and interaction between social classes.
