The article discusses the similarities and differences between the economic theories of Thorstein Veblen and Karl Marx. While some see significant differences between the two, the author argues that these differences are often based on misunderstandings or less important aspects of their work. Veblen's critique of Marx's theories highlights the contrast between their philosophical foundations, particularly in relation to Darwinism and evolution. Despite some congruities, many Marxists and Veblen followers emphasize the fundamental differences between the two thinkers.
