Here's something worth calculating: if you slap on 50% tariffs, it sounds steep. But think about it this way—when your trading partner's currency is sitting 30-40% below fair value, you'd actually need tariffs between 43-67% just to neutralize that currency advantage. The math checks out: undervalued currency creates a built-in competitive edge that tariffs struggle to offset. So that 50% number? It's not arbitrary—it's threading the needle between currency manipulation and trade balance.
