A similar logic applies when we try to compare the

Back in 1992, U.S. presidential candidate Ross Perot warned there’d be a “giant sucking sound” of U.S. jobs heading to Mexico due to the then-new North American Free Trade Agreement (NAFTA). The fact is, offshoring —that is, U.S. companies sending production overseas—had begun long before and
