Look at the most basic need: food. Demand is relatively constant - you need enough to eat, and shouldn&#x27;t eat too much (obviously in practice there is a certain amount of elasticity and differences in demand for different types of food). Supply of food already exceeds demand (look at food waste, supermarkets tossing out ugly produce or burning unsold items to maintain their profit margin). So - demand for food barely goes up, supply continues to exceed demand.
