Final answer:
The concentration of resources in large corporations is a global phenomenon driven by the forces of globalization and is present across different sectors of the global economy, not just confined to the United States or international banking.
Step-by-step explanation:
The concentration of resources in relatively few large corporations occurs throughout the world economy. This process is part of the larger trend of globalization, which involves multinational corporations that control assets, sales, production, and employment. These corporations collect large shares of their capital from a variety of nations and conduct their business without regard to national borders, often concentrating wealth in the hands of core nations and wealthy individuals. Contrary to the idea that they are mainly an American phenomenon or that they deter the presence of multinational corporations, they are a global phenomenon. This concentration can affect economic and political stability, influence governments, and impact the global distribution of wealth. Moreover, it is not just typical to international banking but prevalent in various sectors of the global economy, including manufacturing, technology, and services.
