No. David Ricardo explained all of this in "On the Principles of Political Economy and Taxation" published in 1817. By specializing and taking advantage of comparative advantages, the "pie" is bigger, i.e., more people will have more money to spend.
While Bangladesh makes clothes, and Vietnam makes sneakers(i.e., they are abundant in un-skilled labor), the US has a comparative advantage in R&D, engineering, genetic research, Artificial Intelligence, financial services, etc. (i.e., the US is abundant in skilled labor and capital). Thus, we end up with things like the iPhone (designed in the US and made in China), SB Acoustics drivers (designed in Denmark, manufactured in Indonesia,) etc. The fastest way to having less money to spend would be to have more people in the US making sneakers or speakers.
While David Ricardo’s theory of comparative advantage offers a valuable lens for understanding international trade, it rests on assumptions that often fail to capture the complexities of today’s global economy. The notion that offshoring production inevitably leads to a bigger "pie" for everyone is an oversimplification that overlooks critical economic and social consequences.
In theory, global specialization increases efficiency. But in practice, moving jobs to low-wage countries frequently displaces workers in higher-wage economies, particularly in manufacturing and other middle-income sectors. This job displacement doesn't automatically translate into new opportunities in high-skilled fields like R&D or finance, especially for workers without advanced education or geographic mobility. Instead, many are pushed into low-paying service jobs or permanent unemployment, contributing to rising inequality, economic insecurity, and social discontent.
Ricardo also assumed that capital would remain within national borders, but in the modern global economy, capital flows wherever profits are highest—often to places with the lowest wages and weakest regulations. This dynamic undermines local industries and exacerbates inequality, both within and between countries. At the same time, it increases dependence on complex, fragile supply chains that are easily disrupted, as starkly demonstrated during the COVID-19 pandemic.
Furthermore, the environmental and ethical costs of offshoring are often ignored. Production in low-wage countries may rely on lax labor standards, exploitative practices, or environmentally damaging methods that would be unacceptable in richer nations. These externalities fall outside the neat logic of comparative advantage but have profound consequences for global sustainability and human rights.
The idea that innovation and design remain in high-wage countries while low-wage countries handle manufacturing, as illustrated with the iPhone or speaker components, is also misleading. While it's true that some value stays with designers and R&D teams, a growing share of wealth generated in this model accrues to capital owners rather than workers. As a result, economic growth doesn’t necessarily translate into shared prosperity unless accompanied by robust redistributive policies—something increasingly absent in many developed nations.
Recent global trends further challenge the narrative. The resurgence of industrial policy, strategic reshoring efforts, and supply chain localization in countries like the U.S. and across Europe indicate a recognition that national resilience, employment stability, and sovereignty cannot be sacrificed for theoretical efficiency gains.
Ultimately, Ricardo’s model should be seen as a useful but limited tool, not an infallible law. Blind adherence to it ignores the real-world fallout of global labor arbitrage and masks the growing imbalances it produces. A more nuanced, context-sensitive approach to trade and production is needed—one that values not just efficiency, but equity, sustainability, and long-term social cohesion.
