I think that the question that was raised, I think by Caroll, about the validity of the notion of the "middle-class" is really important. Now, I'm a musician, but for much of the time in my professional life, I "worked" the violin. Doesn't that sound funny? Nobody ever says that. But, you see, we were completely proletarianized. Hence, our union (I mean, the Mafia). One of the emblems of capitalist progress is that more and more professions become proletarianized. Look what's happening to doctors. The working class is not defined by what it does, but the conditions under which it is done.
