Analysis of class should … aim to capture the ambiguity produced through struggle and fuzzy boundaries, rather than to fix it in place to measure and know it. Class formation is dynamic, produced through conflict and fought out at the level of the symbolic. To ignore this is to work uncritically with the categories produced through this struggle, which always (because it is a struggle) exists in the interests of power. Class (as a concept, classification and positioning) must always be the site of continual struggle and re-figuring precisely because it represents the interests of particular groups.
