Re-evaluating Unlimited Wants and Limited Resources: A Critical Scrutiny of Robbins' Definition of Economics

This podcast episode critically examines Lionel Robbins' foundational definition of economics as the science studying the relationship between unlimited wants and limited resources. The speaker argues that both 'unlimited wants' and 'limited resources' are not inherent natural states but are largely socially constructed. Historically, Malthus's theory of population outstripping food supply, driven by unlimited sexual desire and limited land, was disproven by declining fertility and rising agricultural productivity, leading to more optimistic views like John Stuart Mill's 'stationary state' where wants could be satiated. However, modern economics, despite technological advancements, still adheres to Robbins' definition, with the basis of unlimited wants shifting from population growth to insatiable consumption desires, fueled by imagination and promoted by advertising.

The core critique posits that needs are biological, while wants are social, making the idea of naturally limitless wants a 'nonsense.' Society, through competitive consumption and advertising, actively creates and expands wants, and economics, by assuming insatiability, fails to critique these manipulative institutions. Similarly, the notion of naturally limited resources is challenged. The Great Depression, with idle capital and labor, demonstrated that scarcity can be artificial. Scarcity is constantly recreated by human action, such as war, which destroys resources, and by deliberate policy choices like allocating production to armaments, making civilian goods scarcer. Furthermore, general scarcity often ignores issues of distribution, where poverty can exist amidst plenty due to unequal wealth allocation.

The speaker concludes that Robbins' formula, when applied to competitive capitalism and the constant recreation of scarcity, becomes a 'useless tautology.' If economics assumes these conditions, it merely describes a self-fulfilling prophecy rather than analyzing fundamental truths. The failure of mainstream economics to integrate distribution into its analysis is highlighted as a major flaw, contributing to issues like the 2008 financial crisis where insufficient mass purchasing power led to collapse. The episode suggests that if a situation of true general plenty and limited wants ever arose, economics as we know it might become obsolete, as scarcity would no longer be an issue requiring 'economizing.'

Ultimately, the discussion advocates for a re-evaluation of economics' foundational assumptions. It calls for a distinction between needs and wants, a critical stance on institutions that manipulate desires, and a reintegration of distribution into economic analysis. By recognizing the social construction of both wants and scarcity, economics can move beyond a tautological framework to address real-world problems more effectively, challenging the notion that endless growth and competition are inevitable or desirable.

the science which studies the relationship between ends and scarce resources which have alternative uses

what the Robbins definition says is that once a naturally likely to expand faster than the resources available to satisfy them and economics is about the organization you need to make sure this doesn't happen that the population otherwise doesn't starve to death

Malthus was wrong human fertility declined while agricultural productivity rose and economics as a result became considerably or cheerful as the nineteenth-century war on

his second bad habit was to draw large social inferences directly from assumptions about human nature

with needs satisfied the focus of economics has shifted to once the wants of the mind and unlike physical wants the wants of the mind are unlimited because they are located in the minds of the consumer whose imagination was unlimited

needs are biological once a social so the idea that wants are limitless by nature is nonsense

as long as economics pivots on the assumption of insatiability it can't identify much less criticized manipulative institutions like advertising designed to maximize consumption

scarcity like desire is socially constructed

it's the unequal distribution of resources rather than the pressure of population which leads to poverty in the in the midst of Plenty

given competitive capitalism given given the constant recreation of scarcity by human action economics is the science which studies behavior as a relationship between unlimited wants and limited resources which have alternative uses

would we need any economics if there was a situation in which there was general plenty in which scarcity wasn't an issue and I say no we wouldn't need economics at all

if this situation comes about then economics might become as useful to us as dentists
