There are totally polar views of the world economic development. One is the modernization theory and the other is the dependency theory. Which side do you agree with? Although these theories were born in disucssing how developing countries can catch up (or not) to developed countries, you can even apply this to the United States. While the Untied States are leading technologies in certain field (some IT partcularly in software, phermaceutical, defense technologies), in many fields, it started lagging behind some countries in more and more industrial fields (G5 and 6 to China, overall manufacturing skills Japan, S. Korea, Taiwan, China, Germany, Taiwan among others, automobiles to Japan, Germany, South Korea (except for Tesla), environmental technlogies to Japan and some European countries, material technmologies to Japan, semiconductor to Taiwan and South Korea, to name a few). So, in your post, please feel free to add if the Untied States' decline can be explained with the same logic that was used for the modernization and dependeny theories. For example, Biden and Trump both are hesitatnt to join back to free trade based on TPP (Trans Pacific Partnership).
