For some things, I agree it’s important to have domestic capability. For most things, global trade works well for everyone involved, so long as we do it in a cooperative way. The current tariff bullying approach is the worst way of building domestic capability or improving trade relations. More likely the US will sink into a decade or more of stagflation or worse as world markets move on without us, far more easily than we can become self-sustaining.

For your t-shirt example, sure we can buy US made shirts. But the US factories have a limit to what they can produce. Then what? What business person would invest in any new factories in the current environment? Where do they buy the materials to build the factory? (From our trading partners.) Where do they buy the tools and equipment used in the factory? (From our trading partners.) who do they hire to work in the factory? Former government bureaucrats? Immigrants? Oh wait!
