Final answer:
The bourgeoisie was the social class that took ownership of the means of production during industrialization and placed high importance on property values. They emerged from feudalism with the rise of capitalism, contrasting markedly with the proletariat, who were the working class lacking property. Social hierarchies shifted significantly with industrial wealth outpacing traditional land-based wealth.
Step-by-step explanation:
The social class that came to own the means of production during modern industrialization and was primarily concerned with property values is a) Bourgeoisie. This class historically had roots in powerful feudal families and, with the advent of capitalism, became distinguished by owning land, resources, and the capacity for wage labor. The bourgeoisie, as proprietors of factories, land, and businesses, stood in contrast to the proletariat, who were the working class owning only their labor power.
Capitalism and the industrialization transformed social structures, allowing the bourgeoisie to amass wealth and power, which was a shift from the medieval social stratification based on land ownership stemming from a feudal society. The relationship to the means of production thus became a defining element of social identity and hierarchy. With industrial growth, artisans and feudal peasants found their traditional roles and access to production resources undermined, contributing to the rise of the working-class proletariat and the concentration of property and production in the hands of the bourgeoisie.
The aristocracy and other traditional classes faced decline as industrialization unfurled. While land ownership remained significant, it was increasingly supplemented or surpassed by industrial enterprise as a means of wealth accumulation. Over time, the bourgeoisie, with their self-proclaimed moral virtues and work ethic, differentiated themselves not only from the proletariat but also from the older noble classes.
