摘要:This paper proposes that one major explanation of growing inequality in the United States (US) is through the use of the concept of economic surplus. The economic surplus is a neo-Marxian term which combines the traditional Marxian tenet of surplus value with other ways that surplus value can be invested in a mature, advanced capitalist economy. A rising economic surplus that is not absorbed through growing consumer spending, luxury spending or government spending results in stagnant wages and growing inequality via higher levels of underemployment and greater monopoly and monopsony power among a decreasing number of huge, powerful corporations. Therefore, the politics surrounding the growth of inequality in the US has to be understood first by understanding over accumulation of the economic surplus by those at the top of the US capitalist class. This research note gives estimates of the rising economic surplus over the last several decades in the US as well as how these correlate with the level of inequality. The growth of the economic surplus gives rise and form to the politics of inequality and austerity. As time goes by, the politics of inequality and austerity in the US will be manifested by greater corporate influence in the political system, greater political polarization, less government effectiveness, and more debates about welfare spending, corporate taxation, taxes on upper income households, and taxes on wealth.
