Nearshoring into Mexico as an investment theme is premised on the idea that the United States does a splendid job manufacturing high-end goods as well as goods requiring loads of cheap energy inputs. Conversely, it struggles to profitably produce goods requiring significant cheap labour inputs. On paper, Mexico is the perfect partner. The countries enjoy a six-to-one manufacturing wage differential, are close culturally and geographically, and northern Mexico has a decades-long track record of partnering with American manufacturers. A match made in heaven? Not so fast.
