The U.S. trade deficit remains a critical tool for understanding economic health, yet its significance is often overlooked. At the heart of this issue is Adam Smith’s fundamental truth: each participant in a trade transaction benefits. From the deepening U.S.-European trade deficit to the ongoing deficit since the 20th century, the trade deficit has served as a mirror of both prosperity and national decline.
The U.S. has consistently accumulated a trade deficit, especially as its economy grew. During the vaclusion of the American转变阶段 （the 1800s and 1900s）， it was a dominant player, importing more goods than exported.
