Whether the 20 percent holds or is reduced I like the idea of holding their feet to the fire. For years their oligarchy has been dumping their poor on us rather than improve living standards for those without multiple foreign bank accounts.
Plus it sends exactly the right message to American manufacturers who think they can decamp to Nuevo Leon and pay starvation wages to the peons. Our consumer goods may cost more as a result, and the Mexican oligarchy may find their power threatened from within.
But in conjunction with a real, steel wall sunk to bedrock to prevent tunneling… Way cool.
