MEXICO sells America more goods than America sells Mexico, and it enrages President Donald Trump. In 2015 the difference was $58 billion (0.3% of GDP). That is enough, thinks Mr Trump, to justify rewriting the North American Free-Trade Agreement (NAFTA), which allows goods to flow across the Rio Grande free of tariffs. Yet the trade deficit masks bigger figures: America sends almost $240bn in goods to Mexico every year. Were NAFTA to disappear in a renegotiation-gone-wrong, many Americans would pay a price—and not just as consumers faced with dearer avocados. Which American producers would suffer?
墨西哥出售给美国的产品比美国卖给墨西哥的多，这一点让特朗普总统大为恼火。2015年这一差值为580亿美元（占美国GDP的0.3%），这个数据在特朗普看来，已足以证明修改北美自由贸易协定（NAFTA）的合理性，该协定对穿越格兰德河的货物实行零关税。不过贸易逆差背后隐藏着更大的数字：美国每年销往墨西哥的货物价值大概为2400亿美元。假如北美自由贸易协定再次谈判出现问题而失效，很多美国人将为此付出代价——这不仅仅是消费者要承受更贵的牛油果（译者注：墨西哥拥有着全球最大的牛油果生产量）那么简单。那么作为美国厂商，谁将首当其冲呢？
