When transportation and communication costs hit rock bottom, the game changes. Trade imbalances? They're a systemic puzzle, not something you fix country-by-country or sector-by-sector.

This isn't about bilateral trade wars or protecting specific industries. It's about how money flows across borders when barriers disappear, and how one nation's open door becomes the pressure valve for everyone else's excess capital.
