Let's remember that this is not an analysis which simply approves of high bourgeois aesthetics. Bourdieu goes on to analyse the ways these structures of taste are used to maintain boundaries and reinforce social distinctions. The education system is an interesting site for such processes, of course. To be very succinct, his analysis shows that particularly frank and negative judgements are reserved for those from the 'lowest' social origins, and rarely applied to 'those with the richest cultural capital', while those in between receive a curious mixture of euphemism, coded comment, and faint praise. Actual grades awarded are more evenly distributed, but those judgements remain on file.
Dominant groups claim a natural legitimacy for their readings, of course.
These legitimate readings are based on certain concepts and codes which act as 'programmes for perception'. Work on the university suggests that the 'high aesthetic' is confined to a rather powerful minority. Finally, Bourdieu's work can look very old-fashioned, and it can be criticised for using out of date categories, discredited methods, and 'serious' old politics of emancipation. Nevertheless, the old patterns of culture and distinction are breaking down for postmodernists, and so the analysis must be abandoned. In classic terms, these rather particular values are alleged to be universal cultural trends which 'must' be happening.
