Why did two major groups of people lead separate lives?

Two major groups of people often lead separate lives due to differences in culture, socioeconomic status, or geography. These factors create distinct social norms, values, and practices that shape each group's identity and interactions. Additionally, systemic barriers such as discrimination or lack of access to resources can further entrench these divisions, making it challenging for the groups to connect or integrate. Consequently, these disparities reinforce a cycle of separation and misunderstanding between the groups.
