There are two main ways humans can generate income: sales power and volatility. Added value is continuously created through production, which involves actions to generate this added value. By adding new layers of value to basic ones, additional value is created—for example, making bread from wheat flour. The ability to persuade someone to buy this added value is known as sales power.
