> the proletarianisation of academic labour?
The overwhelming number of "academic workers" were proletarianized long ago. A very small number at a handful of elite universities receive a salary that cannot conceivably be thought of as coming out of variable capital but is (under the judicial form of a wage) a share in surplus value. They are not "middle class" either, they are marginal big bourgeoisie. The rest (however false their consciousness may be -- and currently it tends to very false indeed) are all proletarians.
