The statement highlights the interdependence of sale and purchase in the business cycle:
1. Mutual Dependence: A sale can only occur when someone purchases the product or service. Without buyers, sellers cannot exist.
2. Flow of Goods and Money: Businesses purchase raw materials to produce goods, which are then sold to customers. This creates a flow of goods, services, and money in the economy.
3. Economic Activity: The cycle of purchase and sale is the backbone of economic activity, enabling the exchange of resources and wealth creation.
For example, a farmer sells crops to a retailer who purchases them to sell to customers. Both activities are necessary for the economy to function.
