Scraps: Identity through popular culture

This is the start of an argument I'm not likely to finish:

Popular culture is the dominant point of reference through which people understand their lives. This is especially worrying considering the narrow range of expression offered by the media, compared to the variety expressed in real life.
If popular culture is seen as television drama, pop music and fashion, there are a number of groups excluded or marginalised from those areas, such as the elderly, the poor, and the foreign. Without any way to identify with popular culture, these groups must find other ways to understand their lives, set apart from the mainstream society.
