Why Trump’s tariffs didn’t bring manufacturing back to America

Summary

Harvard Business School professor Willy Shih argues that broad tariffs fail to restore American manufacturing because global supply chains naturally route around trade barriers. Instead of returning assembly jobs, blunt tariffs often trigger circumvention through countries like Mexico and raise domestic costs across interconnected industries.

Key Takeaways

1. When we put up these trade barriers, the first reaction tends to be, “How can I circumvent that?”
2. I think we have to start with a core principle that the US is a high-cost country. Therefore, if you want manufacturing jobs coming to the US, then you’ve got to have high labor productivity.
3. Before I build a factory, I want to know that I’m going to have stable demand for a couple of years, at least until I have a chance of earning a return on that thing.

Credibility & Bias Reasoning

Credibility assessment: The piece is an extensive interview with Willy Shih, a Harvard Business School professor and former supply chain advisory committee member. The claims reflect his academic expertise and direct industry observations across global manufacturing hubs. Sourcing is transparent and relies on Shih's personal field research and economic analysis.

Bias assessment: Pro-Global Trade Economic Realism. The conversation primarily views trade and industrial policy through classical economics, favoring specialization and market efficiency over protectionist interventions. Both host and guest critique short-term tariffs and political promises to reshore manual manufacturing. The perspective remains grounded in supply chain mechanics rather than overt partisan alignment.

Note: Relies on the analysis and professional observations of an academic supply chain economist.
