a revolutionary transition from capitalism to socialism

In Political Economy for Socialism, and in the chapter called, “Marx’s Socialism”, Professor Itoh describes what we could call a transformation of everyday life, one that represents a revolutionary transition from capitalism to socialism. Firstly, how are we to think of the all-important category of “labour power” in this transformation and transition? Second, how are we to think of the differences between ‘reform’ and ‘revolution’? Finally, what is the fate and/or destiny of working and labouring in the socialist world that Marx envisioned, and that Itoh is further proposing? In your response, please refer to Itoh’s text, and/or to Marx’s text (which Itoh refers to), i.e., Critique of the Gotha Program), to support your argument.
