You don’t have to be middle class to be a postmodern philosopher but it helps

Mike Featherstone in Consumer culture and postmodernism, says that Habermas’ ‘dissatisfaction with Foucault and Derrida (and by association with Deleuze and Lyotard) was for endorsing a decentred boundless subjectivity, content to experience expressive intensities that were effectively derived from the postmodernist avant-garde which had sought to break down the boundaries between art and everyday life and hence gave primacy to aesthetic experiences and gestures over morality and communicative modes of truth’ (31). So some forms of postmodern philosophy actually advocate forms of subjectivity that are found in the middle classes of consumer culture. These postmodern philosophers thereby reveal their class situation. (This is somewhat ironic given many of them have Marxist positions). Admittedly most consumers may have learned to make ‘style’ the most important part of their ‘lifestyle’ but this suggests that their theories may be much less useful for understanding other subcultures in society.
