The Four Factors of Production
Every good or service you've ever consumed was made using some combination of four factors of production. Understanding these helps explain how our economy actually creates the things we need and want.
Land includes all natural resources - not just soil, but oil, minerals, forests, rivers, and even climate. Labour is human effort, from manual work to brain surgery to professional football. Capital means goods created to make other goods - machinery, factories, computers, even schools (but not money itself).
Enterprise is the special factor that brings everything else together. Entrepreneurs take risks, start businesses, and organize the other factors to create products profitably. Without enterprise, the other factors would just sit there unused.
Different products need different combinations of these factors. A box of vegetables needs lots of land and labour but little capital, while a car needs massive amounts of capital and relatively less land.
Remember: Capital in economics means physical things that help produce other goods, not money or financial assets.
