Why Did Mr. Trump Oppose Globalization? An E-CARGO Approach

Everybody knows that Mr. Donald Trump, the 45th President of the United States of America (USA), was against globalization. There are numerous arguments about this topic around the world among renowned politicians and economists. This article presents a new viewpoint from group multirole assignment (GMRA). In this article, we establish a model for simulating the assignment of grand capitals over the world with the help of the Environments—Classes, Agents, Roles, Groups, and Objects (E-CARGO) model and the GMRA model. To support the conclusions, we simulate the situations of globalization and nonglobalization, compare, and analyze the simulation results with a revised GMRA (RGMRA) model. This article contributes a new formalization of a new role assignment problem (RGMRA), a novel way to study globalization, and a clear and evident conclusion that globalization is not beneficial for the USA from the point of view of capital investment.
