period and after World War II. One of the important sections is Chapter 2: "Economic Development and Democracy." Larry Diamond and Gary Marks argue that "Lipset's assertion of a direct relationship between economic development and democracy has been subjected to extensive empirical examination, both quantitative and qualitative, in the past 30 years. And the evidence shows, with striking clarity and consistency, a strong causal relationship between economic development and democracy."[2] In Chapter V, Lipset analyzed "Fascism"—Left, Right, and Center, and explained that the study of the social bases of different modern mass movements suggests that each major social stratum has both democratic and extremist political expressions. He explained the mistakes of identifying extremism as a right wing phenomenon, and Communism with the left wing phenomenon.

He argued that the reason for this divergence is that the initial patterns of colonization, the subsequent process of economic incorporation of the new colonies, and the wars of independence varied. The divergent histories of Britain and Iberia are seen as creating different cultural legacies that affected the prospects of democracy. Public affairs Lipset left the Socialist Party in 1960 and later described himself as a centrist, deeply influenced by Alexis de Tocqueville, George Washington, Aristotle, and Max Weber. He became active within the Democratic Party's conservative wing, and associated with neoconservatives, without calling himself one. Lipset was vice-chair of the board of directors of the United States Institute of Peace, a board member of the Albert Shanker Institute, a member of the US Board of Foreign Scholarships, co-chair of the Committee for Labor Law Reform, co-chair of the Committee for an Effective UNESCO, and consultant to the National Endowment for the Humanities, the National Humanities Institute, the National Endowment for Democracy, and the American Jewish Committee.
