¹ Outside the economic field, the idea of a “living wage” has been discussed extensively. For different perspectives, see Sen, A., Development as Freedom (Oxford 1999)Google Scholar; Ryan, J.A., A Living Wage: Its Ethical and Economic Aspects (London 1915)Google Scholar.

² Neoclassical economics super-ceded classical political economy, but the relevance of the latter for legal purposes remains. This is so, not least, due to its influence on minimum wage legislation during the twentieth century (see below), and given the continued relevance of these arguments to present legal forms.

⁹⁹ How far this was achieved in practice, however, is an open question. The point being made refers to the conceptual structure of the Wages Councils Act, and thus, its potential as a mode of regulating pay. That different age groups are currently paid a different rate – but still incur broadly similar living costs – further shows that this “living wage” is not seen to perform a subsistence function in the same way as had the minimum rates of remuneration envisaged by the Wages Councils Act where, through collective bargaining, rates were expected to vary as between trades, classes of workers and geographical locations.
