The difference between populism and progressivism lies primarily in their approaches to politics and social change. Populism often emphasizes anti-establishment sentiment, appealing to the 'common people' against perceived elites; it can be found across the political spectrum. In contrast, progressivism focuses on systemic reform, advocating for social justice, equality, and government intervention to address societal issues. While populism may utilize a simplified narrative to garner support, progressivism tends to engage with complex policy analyses to promote sustainable solutions.
