Interest-group capture occurs when an interest group gains excessive influence over the policies and decision-making processes of the government.
Step-by-step explanation:
Interest-group capture occurs when an interest group gains excessive influence over the policies and decision-making processes of the government. It happens when the interest group successfully manipulates the political system to serve its own interests, often at the expense of the broader public interest. Interest-group capture can occur through various means, such as lobbying, campaign contributions, and forming alliances with politicians. For example, a pharmaceutical industry interest group may capture the government's decision-making process on healthcare policies, leading to policies that favor the industry over the interests of consumers.
