  1. What is free trade, why has it grown so much since WW II, why does it often lower costs and increase efficiencies in the long term (while losing some jobs and lowering some wages in the short term), why do most liberals push it while some realists fear it and often Marxists and feminists condemn it, and why is it again under attack?

ESSAY

  1. What is the Liberal International Economic Order (LIEO), how did the creation of the World Bank (WB), the International Monetary Fund (IMF), and the General Agreements on Tariffs and Trade (GATT)/World Trade Organization (WTO) all aid it, and how did it all reduce economic nationalism, which created massive economic growth and wealth but also economic insecurity and local job losses?
