Will sneaker makers be paid $20 an hour? Or are you saying my salary will suddenly double if sneakers are only made in America?
Sub assemblies for military hardware?
I agree, we shouldn't depend on foreign suppliers for vital military gear.
Maybe not double but certainly increase sharply. It doesn't matter if a price is high if your wage rises with it. Money doesn't have any other value than what men put on it. With internal trade, prices will not rise beyond the prevailing wage. The market forces will keep the two in line. Job abundance and relative worker scarcity will keep the wages in line with prices.
We don't have to wonder about this process. It has already worked. What's the point of changing it?
