Conflict theory and functionalist theory provide different perspectives on society. Conflict theory, developed by Marx, views society as consisting of groups that compete over scarce resources, leading to conflict and struggle. Functionalist theory, developed by Durkheim, views society as a system of interrelated parts that work together to maintain stability and equilibrium. Private schools can be seen through either lens - conflict theory may see them as perpetuating class divisions, while functionalism may see them as fulfilling important social functions and helping to socialize children.
