In the video, two key concepts are the means of production and labor. So this means that production refers to physical tools, machines, buildings, land, and raw materials that are made by a human being. These are the things needed to produce commodities, but they are usually owned by a capitalists in a capitalist system.
In video 5.1, value is understood as the amount of socially necessary labor time required to produce a commodity. According to the video, the value does not come from how useful something is or how much someone is willing to pay for it. Instead, value comes from the average amount of labor time needed to produce something under normal working conditions and with average skill and technology. For example, if it takes many hours of skilled labor to produce a piece of furniture, it has more value than something that takes only a few minutes to make.
According to the video, labor and value are directly connected because labor is what creates value. In the Labor Theory of Value, the value of a commodity is determined by the socially necessary labor time required to produce it. The relationship between labor and value is therefore foundational: value exists because labor has been applied.
According to the video, the key difference between labor and labor power is that labor is the actual work performed by a human, while labor power is the worker’s capacity or ability to work. Labor power is what workers sell to employers in a capitalist system. Once the capitalist purchases labor power (through wages), the worker then performs labor during the workday. The important distinction is that labor power can produce more value than it costs to buy. For example, a worker might be paid $150 for a day’s work, but during that day they may produce $300 worth of value.
Surplus value is the extra value that workers create beyond what they are paid in wages. According to the video, when workers sell their labor power, they are paid a wage that covers the cost of their survival (food, housing, basic needs). However, during the workday, they produce more value than that wage equals. The difference between the value they create and the wages they receive is called surplus value. This surplus becomes profit for the capitalist. Surplus value is important in the study of social classes because it explains how wealth is generated and why inequality exists under capitalism. For example, a worker in a factory who is paid $160 for an 8-hour shift. During that shift, the goods they produce are sold for $500. After subtracting the cost of materials and machinery, there is still value left over that exceeds the worker’s wage. That remaining amount is surplus value. It does not go to the worker who created it; it goes to the owner of the business.
