Creativity of power Book

First off the description of "Dialectal stories and poems by New York City black and Spanish-speaking children edited from tape recordings taken in the classroom" is incorrect. This is a book examining the necessarily counter-revolutionary aspect of economic systems--though it seems to consider capitalism the evil and leaves socialism unexamined perhaps stemming from an immediacy of writing within a capitalism-associating society.
It examines art as a possibility of revolt so long as the issue isn't confused by attempting an affirmative art ("proletarian art" as well as "commodity (bourgeois) art" are defined as propaganda, which I think is a fair assessment in terms of the argument). Following this, Art negates; refusing the immediate, the society form which it sprang, by transforming characters, attributes, whatever to universals. This transcendent character makes Art incapable of affirming a society, excepting the possibility of a transcendent (classless?) future society, though it is firmly between the lines that this potential society will remain only potential.
I think the most interesting parts for me were the occasional discussion of the re-appropriation of the offensive, of the subcultural as marketable and thus affirming the structures they would seem to protest. I'm not done chewing on that, but I think it's a worthwhile assertion, and a challenge: How does one create something to combat or make impossible this appropriation?
