How does the labor theory of value relate to the modes of production in historical materialism?

The labor theory of value suggests that the value of a good or service is determined by the amount of labor required to produce it. In historical materialism, which studies how material conditions and economic factors shape society, this theory helps explain how different modes of production, like feudalism or capitalism, affect social relationships and class structures. For example, in a capitalist society, workers produce goods but receive only a fraction of the value they create, leading to a divide between the wealthy owners and the laborers. This relationship shows how economic systems can influence people's lives and societal organization over time. By understanding these connections, we can see how changes in production methods impact social dynamics and history itself.
