This document provides an overview of the key concepts regarding economic prosperity at the individual, national, and global levels. It defines prosperity as having secure access to life's necessities as well as the ability to purchase non-essential goods. True national prosperity exists when a strong majority of citizens can consume beyond basic needs. Few countries have achieved widespread affluence, generally defined as an annual per capita income over $10,000. While economic growth does not guarantee national prosperity, factors like health, education, security, and freedom contribute to quality of life assessments. Individual prosperity is also multifaceted and depends on conditions like entrepreneurship opportunities, access to capital, and public goods that allow for maximized productivity.
