Writing in the  Economic Record in 1938, Melville said ‘Zero interest is a limiting, but unattainable,  value analogous to infinity.’ [6] He went on to argue that ‘the notion that a zero rate of interest is possible assumes that there is a practicable limit to the amount of useful material which can be profitably employed by society’.
To reinforce this point, he went on to write that at zero interest: ‘Roads would be levelled and straightened regardless of cost. In some places mountains would be dug away and valleys filled to provide residential and agricultural land.
