I have never been comfortable with lamenting over the marginalisation of Marxism in academia, in which many comrades time to time indulge. In fact, there is no such marginalisation happening globally – just look at the publishing projects of Marxists throughout the globe, with books priced exorbitantly. Of course, this Marxism is not meant for activists – they can be fed with free blogs and free tweets/fb entries (even these are accessible to a tiny minority only)! A senior ‘Marxist’ in Delhi once told a students conference in the early 1990s, how much she and her colleagues have contributed in Marxism – the only job left for leaders and activists now is to put that knowledge in use. Perhaps the neoliberal rightwing assault on this academic comfort (and liberalism, which liberalised Marxism too) gives an opportunity to liberate Marxist theorisations, regrounding them in real class struggle and proletarian practice (even in academia).
David Laibman correctly historicised this state of Marxism and its implications in his 1997 book, Capitalist Macrodynamics:
The shifts in political and economic power have… been accompanied by ideological transformations as well. Marxism, having been largely removed from its earlier position of influence in the labor movement and other social spheres, has taken refuge in the academy. There, under intense intellectual pressure, a certain fragmentation has taken place, as the formerly unitary Marxist world view has conformed to the disciplinary specialisations: thus we have ‘Marxist sociology’, ‘Marxist economics’, and so on. The unifying generalizations of historical materialism have also come under continuous fire, as Marxists have retreated to more ‘defensible’ positions.
