The future of the working classes: a comparison between J.S. Mill and A. Marshall

Both J. S. Mill and A. Marshall had a lifelong interest in the living conditions of the working classes and theorized the possibility of a new age, characterized by a widespread mental and moral cultivation. This paper compares the precise arguments put forward by them in the period ranging from Mill's to Marshall's Principles, against the background of the evidence of social and human progress at their times. It is argued that, at different stages and with different specific arguments, their predictions relied on self-reinforcing mechanisms, in which a better life was the cause, no less than the effect, of progress. In order to make similarities and differences more transparent from a logical point of view, two simple mathematical formulations are proposed.
