Capitalism was an economic system based on ownership of the means of production by individuals competing on a free market. The Eighth Doctor was assumed to be a capitalist by several people in Spain. Fitz Kreiner branded Anji Kapoor a "capitalist pig" who was in turn surprised by how similar career communists and career capitalists were.

While fighting in the Spanish Civil War, Bob Edwards used a megaphone to shout out lengthy political arguments about the capitalist system. (PROSE: History 101)
