The rose-tinted view of globalization holds that free trade maximizes profits, efficiency, and economic growth by leveraging the power of comparative advantage. In this idealized trade system, countries specialize in products that they can make more easily or cheaply than others, and rely on the free flow of goods to import the rest. The iPhone is often cited as an example: the design, engineering, and marketing of the device is done in the US, while assembly is outsourced to China, and key components are sourced from Samsung of South Korea. Supply chains criss-cross the globe. Everyone gains. Wall Street is happy with bumper quarterly reports.
