The authors take the thesis that prior to World War I, the world effectively lived in a state of globalization, which they term the First Era of Globalization. The authors define globalization as periods in which free markets predominate and countries place few, if any, limits on exports, immigration, imports, or information exchanges. Overall, they see globalization as a positive movement that improves the standard of living for all the people connected to it, from the richest to the poorest. According to the authors, the rise of communism and fascism, not to mention the Great Depression, nearly extinguished capitalism, which rapidly lost popularity.
