It doesn't matter if they have a relationship with each other. It's just that they have one thing in common is to measure the magnitude of all values.
Money, with gold next to it, is because it specifically refers to the size of the base value of a certain stage with a unique metal, such as gold, silver and copper. Because in addition to the significance of the size of the base value, but also because of their own value and the corresponding value of the base, such as one or two gold target value of the object is equivalent to one or two gold, and will not be more or less at the bottom.
Currency is a unique value size of goods, such as shells. Such goods may or may not have value, for example, in a special period of time grain can become a universal currency, while relative shell grain is valuable, shells have no value. Therefore, barter is essentially money exchange.
Banknotes are entirely a substance of virtual base value. It relies only on the size of the symbol base value it carries, and its own value is almost negligible compared to the size of the value it represents, such as paper money and ultimately electronic money.
Capital, the essence of all resources is called capital, and the reason why all resources are called resources is their value, so the essence of capital is value. For example, there are many resources on Mars that cannot be used as capital because their value cannot be used. Capital can be transformed into any resource, manpower, equipment, site, raw materials, energy, etc.
It can be seen that the common value of money, money, and banknotes is fundamental, and it is determined that capital often appears in its face. But capital itself is not a money currency banknote, but only a value withdrawal with its characteristic underlying nature.
It is assumed that the value of labor and equipment is the same. Taking the grinding copper mirror as an example, it takes a month for a person to manually grind a copper mirror, assuming that he can earn 500 yuan. Installing a piece of equipment can grind out 1,000 yuan a month and earn 2 yuan per piece. People and equipment were divided equally to 1,000 yuan each, and everyone was very happy.
However, when 10 equipment is invested, each equipment is one person, each person is 1000 yuan a month, and the equipment side gets 10000 yuan. At this time, contradictions appeared, and some people felt that the equipment side made more money. Especially when the equipment side does not invest in the equipment but invests the same money and currency banknotes as the equipment, people have more opinions: "Your money will make more money than we do in one turn, it is too unfair." ”
The deeper meaning of this contradiction is jealousy. Even if the equipment side cuts the income by half to benefit the workers, they still feel unfair. Deep down, they both earn the same income.
At this time, some people put forward a theory that "the equipment cannot be polished without workers, and the equipment side exploits the surplus value of the workers' labor", which will certainly be supported by the majority of workers, even if no one says clearly what "surplus value" is, people still believe that there is surplus value. Just as people believe that God exists, they expect "surplus value" to bring benefits to themselves in the same way as God. As for what it is, how it is calculated and how it is identified does not matter at all!
In this way, labor relations are irreconcilable, especially the slogan "capital is naturally bloodthirsty" came out. People's eyes are full of blood, and they have long forgotten the blood and sweat of grinding a copper mirror a month.
