Based on my understanding of the material covered in this portfolio, I disagree with Sinclair Lewis's assertion that a dictator could never rise to power in the United States. Throughout history, we have seen examples of democracies falling to authoritarian regimes, such as in Germany with Hitler, Italy with Mussolini, and more recently in countries like Venezuela. The United States is not immune to the dangers of authoritarianism, as seen in the rise of populist leaders and the erosion of democratic norms.
Sinclair Lewis is mistaken in his belief that America's size would prevent a revolution from occurring. In fact, the size of the country could potentially make it more difficult for the government to maintain control in the event of widespread unrest. Additionally, the polarization of American society, the erosion of democratic institutions, and the rise of extremist ideologies all create fertile ground for an authoritarian leader to rise to power.
Therefore, based on the historical examples and current trends discussed in this portfolio, I believe that Sinclair Lewis's assertion that a dictatorship could not happen in the United States is incorrect. The threat of authoritarianism is very real and must be taken seriously in order to safeguard our democracy.
