What principle states that individuals have the right to control their possessions?

The principle that states individuals have the right to control their possessions is known as Private Property Rights. This concept is fundamental to a market economy, as it ensures that individuals can own, use, and manage their property without interference from others, including the government.

Private Property Rights provide incentives for people to manage their resources responsibly, invest in property improvements, and engage in trade. When individuals feel secure in their ownership, they are more likely to take care of their possessions and contribute to economic growth, as they can freely exchange their goods and services in the marketplace.

In contrast, the other options relate to different aspects of economics that do not specifically address individual control over possessions. Social Security deals with government-provided financial support, Economic Growth refers to the overall increase in the economy's output, and Public Goods and Services relate to resources that are made available to all members of society, which do not emphasize individual ownership. Understanding the concept of Private Property Rights is essential for grasping how economies function and the role of individuals within that framework.
