In his early books, such as "The System of Objects", "For a Critique of the Political Economy of the Sign", and "The Consumer Society", Baudrillard's main focus is upon consumerism, and how different objects are consumed in different ways. At this time Baudrillard's political outlook was loosely associated with Marxism (and Situationism), but in these books he differed from Karl Marx in one significant way. For Baudrillard, as for the situationists, it was consumption rather than production that was the main driver of capitalist society.
