The irrepressible Cafe Hayek man makes his point:
When Beijing subsidizes Chinese exports or tariffs Chinese imports (or both) it does indeed tilt the playing field. But it tilts that field in favor of Americans (and others who who buy Chinese exports) and against its own citizens.
These interventions by Beijing raise our real incomes: our dollars buy more from China. And any resulting job losses in America mean that resources are released to produce goods and services here that were previously too costly to produce.
Whenever a trading partner insists on giving you more for your money, you are made better off. This fact isn’t altered if your trading partner happens to live abroad.
This his main argument vs. Trump, and my only one.
