Ramaswami: As far as the quality of the working class related to its leading role, it was explained that the revolutionary role of the class arose in its relationship with the means of production and it was the only class which had no ownership of means of production whatsoever. While one could not underestimate the weakness prevailing among this class, modern revolution was not possible without its leading role. This is more relevant in Indian context where the working class has to build the axis of democratic revolution by organising other toiling masses especially rural poor. Further this class has to be educated of its leading role by the organisation which happens to be the Communist Party.
