The document compares the economic theories of Karl Marx and Adam Smith, emphasizing their differing views on consumption and capitalism. While both theorists acknowledge the importance of consumption and labor in assigning value, Smith promotes capitalism and the idea of an 'invisible hand' guiding market forces, whereas Marx critiques capitalism for exploiting workers and advocates for a communist society. Ultimately, the analysis suggests that Smith's ideas may be more relevant to contemporary society than those of Marx, especially in the context of historical outcomes in socialist regimes.
