Final answer:
Marx and Mill both criticized capitalism but from different perspectives; Marx from a class struggle viewpoint and Mill from individual liberty. They shared concerns about the effects on the individual, with Marx focusing on worker alienation and Mill on personal freedom.
Step-by-step explanation:
Karl Marx and John Stuart Mill both criticized capitalism, but their critiques differ significantly. Marx saw capitalism as an exploitative system that creates class conflicts and believed it would eventually lead to its own demise, giving rise to a classless society. Marx's view was based on the material conditions and the contradictions he perceived within real-world phenomena. Mill, on the other hand, criticized capitalism from a perspective of individual liberty, suggesting that unrestrained capitalism could lead to a tyranny of the majority and undermine personal freedom.
One criticism they shared concerns the effects of capitalism on the individual. Marx pointed to the alienation of the worker from the work, while Mill was concerned about the stifling effect of industrial society on individual development. As to which critique and alternative to capitalism are more compelling, this remains subjective and can depend on individual values and perspectives on freedom and equality.
