Final answer:
Marx and Engels in 'The Communist Manifesto' were concerned with the domination of the wealthy over the poor and saw the history of societies as a history of class struggles.
Step-by-step explanation:
Karl Marx and Friedrich Engels, writing in The Communist Manifesto, were primarily concerned with B. The domination of the wealthy over the poor. In their view, the bourgeois—those who own the means of production—exert control over the proletariat, or the working class, leading to a history of class struggles. Marx and Engels predicted a societal transition from capitalism to socialism, and ultimately to communism, where property and wealth would be collectively owned by the community, thereby ending class conflicts.
Their manifesto critiqued the capitalist system for its exploitation of workers and suggested that a revolution would be necessary to overthrow the oppressive structures and realize a classless society. Marxism, therefore, centers on the idea that societal change can only be achieved through confronting and remediating the power imbalances between the ruling class and the working class.
