Donald Trump has been President of the US for about four months, implementing policies that have stirred both the world and the US economy with resistance and criticism.
Trump envisions making America a greater economic power, despite concerns about the already substantial GDP and the limitations of his four-year term compared to President Roosevelt's longer tenure.
Similar to Roosevelt's New Deal policies in the 1930s, Trump's approach challenges existing orthodoxies, leading to intense opposition that parallels the paradigm shifts described by Thomas Kuhn in science.
Both Roosevelt and Trump faced backlash for their disruptive ideas, with Roosevelt's revolutionary policies eventually becoming orthodox post-World War II, reflecting the cycle of resistance to new ideas followed by the establishment of a new paradigm.
