Frederic Jameson is a Marxist theorist who argues that changes in the economic base of society, from industrial capitalism to late capitalism to an information economy, correspond with changes in the cultural superstructure. Specifically, he notes a shift from production to consumption that is exemplified by postmodern art like pop art, which emphasizes commodification and pastiche over authenticity and critique. Jameson views postmodernism as a symptom of late stage capitalism defined by consumption rather than a revolutionary response.
