Final answer:
Karl Marx's theory of Marxism described the bourgeoisie as a wealthy commercial class that arose from capitalism, exploiting labor and accumulating excess wealth, leading to class conflict and eventual societal change towards socialism.
Step-by-step explanation:
Karl Marx, in his seminal works such as Das Kapital and The Manifesto of the Communist Party, articulated a perspective on the creation of a wealthy commercial class, known as the bourgeoisie. This class arose from the capitalist system where they owned the means of production. Marx argued that the bourgeoisie were primarily motivated by the desire to exploit labor, paying workers (the proletariat) less than the value their labor produced and thus amassing excess wealth. This wealth was used to purchase more resources and influence political systems to their advantage. Marx believed this process was inherently unfair and predicted that it would lead to the collapse of capitalism and the eventual uprising of the proletariat, who would then establish a more equitable socialist system.
