"Class," thanks to the media and to mainstream sociology, along with nostalgic marxists," has become a pretty vague term itself. If (as _almost_ all versions of marxism hold in theory) class is a social relation, and moreover a social realtion constantly undergoing change, and NOT simply a convenient way to classify people as one classifies marbles (red in this can, blue in that, pink in the next one, mottled in the big one over there), then to say that the "middle classes could become a revolutionary class" is utter nonsense, since the social realations pointed to are _working class" relations. THis is merely a confusing way of getting at the point that one huge sector of the modern working class (a) do not work in factories or mines and (b) are pretty well off in comparison to 19th c. proletarians.
