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.
