Problem: Background: Roberto Mangabeira Unger (; born 24 March 1947) is a philosopher and politician. He has developed his views and positions across many fields, including social, political, and economic theory. In legal theory, he is best known by his work in the 1970s and 80s while at Harvard Law School as part of the Critical Legal Studies movement, which is held to have helped disrupt the methodological consensus in American law schools. His political activity helped the transition to democracy in Brazil in the aftermath of the military regime, and culminated with his appointment as Brazil's Minister of Strategic Affairs in 2007 and again in 2015.
Context: Unger's critique of economics begins with the identification of a key moment in economic history, when the analysis of production and exchange turned away from social theory and engaged in a quest for scientific objectivity. In Unger's analysis, classical economics focused on the causal relations among social activities, which were connected with the production and distribution of wealth. Classical economists asked questions about the true basis of value, activities that contributed to national wealth, systems of rights, or about the forms of government under which people grow rich. In the late-nineteenth century, in response to attacks from socialist ideas and debates about how society works, and as a means to escape the conundrums of value theory and to answer how values could become prices, marginalist economics arose. This movement in economics disengaged economics from prescriptive and normative commitments to withdraw the study of economies from debates about how society worked and what kind of society we wanted to live in. For Unger, this moment in the history of economics robbed it of any analytical or practical value.  Unger's critique of Marginalism begins with Walras' equilibrium theory, which attempted to achieve a certainty of economic analysis by putting aside normative controversies of social organization. Unger finds three weaknesses that crippled the theory: foremost, the theory claimed that equilibrium would be spontaneously generated in a market economy. In reality, a self-adjusting equilibrium fails to occur. Second, the theory puts forth a determinate image of the market. Historically, however, the market has been shown to be indeterminate with different market arrangements. Third, the polemical use of efficiency fails to account for the differences of distribution among individuals, classes, and generations.  The consequences of the marginalist movement were profound for the study of economics, Unger says. The most immediate problem is that under this generalizing tendency of economics, there is no means by which to incorporate empirical evidence and thus to re-imagine the world and develop new theories and new directions. In this way, the discipline is always self-referential and theoretical. Furthermore, the lack of a normative view of the world curtails the ability to propose anything more than a policy prescription, which by definition always assumes a given context. The discipline can only rationalize the world and support a status quo. Lastly, Unger finds that this turn in economics ended up universalizing debates in macroeconomics and leaving the discipline without any historical perspective. A consequence, for example, was that Keynes' solution to a particular historical crisis was turned into a general theory when it should only be understood as a response to a particular situation.

In Unger's analysis, classical economics focused on the causal relations among social activities, which were connected with the production and distribution of wealth.
