Using pictures to discuss the economic law that things are rare and precious?

The phenomenon of "scarcity is the most valuable thing" in commodity economic relations mainly refers to the influence of supply and demand on prices, which is the concrete embodiment of the law of value.

The law of value is the basic economic law of commodity production and commodity exchange. The law of value requires the principle of equivalent exchange in commodity exchange, which is realized through the two-way restriction of price and supply and demand. Therefore, when demand exceeds supply, prices will rise, thus expanding production; Oversupply will depress prices, thus reducing production. The law of value requires the principle of equivalent exchange in commodity exchange, which is realized through the two-way restriction of price and supply and demand. Therefore, when demand exceeds supply, prices will rise, thus expanding production; Oversupply will depress prices, thus reducing production.

For example, from an economic point of view:

1. The demand curve tells us that scarcity is the most valuable thing, and more goods are worthless;

2. The law of diminishing marginal utility tells us that the marginal utility brought by too many commodities will be less and less, or even negative;

It must be clear that "things" here, like commodities, must be valuable and useful.
