transnational capitalist class (TCC)

The U.S. political scene has been undergoing a facelift in an effort to restore the decreasing legitimacy of the transnationally-oriented capitalist class. This transformation has been characterized by a right wing that has sought to portray itself as economically nationalistic in an attempt to expand support among the working class (primarily, among working class whites) whose economic stability has dwindled during the neoliberal era.
Why is this the case?

Globalization of trade and central banking has propelled private corporations to positions of power and control never before seen in human history. Under advanced capitalism, the structural demands for a return on investment require an unending expansion of centralized capital in the hands of fewer and fewer people. The financial center of global capitalism is so highly concentrated that less than a few thousand people dominate and control $100 trillion of wealth.
