The document discusses theories about how interest groups influence public policymaking. It describes pluralism, where many diverse interest groups compete to influence government. However, some groups have more resources and connections, potentially tilting policy in their favor.

Both theories have critics, and most real-world systems incorporate elements of pluralism and neo-corporatism depending on a country's unique political and historical context.
