How do Marx's and Lenski's theories differ in their emphasis on societal change?

Marx's theory focuses on conflict between social classes as the main driver of societal change. He believed that the struggle between the working class, or proletariat, and the owning class, or bourgeoisie, leads to significant transformations in society. For example, when workers unite to demand better wages, this can challenge the existing power structures and create new social conditions. In contrast, Lenski's theory emphasizes technology and the level of resources available in a society as the primary factors that drive change. He argues that as societies develop new technologies, they evolve and change in ways that are not solely based on class conflict, but also on how these advancements affect social organization and relationships.
