45: The Economics Behind the Boom in Anti-Immigration Sentiment

Episode Summary

Executive Summary: The episode examines how immigration affects the U.S. and U.K. economies, arguing that immigration generally boosts growth, innovation, and fiscal health by expanding labor supply, filling skill gaps, and enabling complementary job creation. Economist Giovanni Peri says fears about wage suppression and job loss are overstated in the aggregate, though some low-educated older workers can face short-run displacement. The conversation also explains why immigration remains politically charged.

Main Topics: Immigration as an Economic Force (Priority: 5/5): The hosts frame immigration as a major driver of labor-force growth, business formation, consumer demand, and overall economic expansion in the U.S. and, to a lesser extent, the U.K. Low-Skill Complementarity vs. Job Competition (Priority: 5/5): Peri argues immigrants often fill manual, service, agricultural, and construction roles that native-born workers increasingly avoid, allowing firms to expand and create additional jobs for Americans. High-Skill Immigration and Innovation (Priority: 5/5): The discussion highlights how educated immigrants, especially scientists, engineers, and tech workers, contribute disproportionately to productivity, technological progress, and sector growth such as Silicon Valley. Wages, Labor Markets, and Adjustment (Priority: 4/5): The episode addresses the standard supply-and-demand concern that more workers depress wages, with Peri emphasizing that long-run labor-market adjustment, specialization, and capital investment weaken the negative effect. Fiscal Impact and Public Services (Priority: 4/5): Peri explains that high-skilled immigrants tend to be net contributors to public finances, while many undocumented low-skilled workers pay taxes but have limited access to benefits, making the overall fiscal effect likely positive. Why Immigration Becomes Politically Explosive (Priority: 4/5): The hosts connect anti-immigration sentiment in the U.S. and Brexit-era U.K. to stagnant wages, housing pressure, austerity, cultural anxiety, and a tendency to blame immigrants for broader economic change. Historical Perspective and Policy Constraints (Priority: 3/5): The conversation situates current backlash within recurring U.S. historical cycles of nativism and notes that modern immigration is highly regulated, unlike earlier eras of freer entry.

Key Arguments: Immigration increases labor-force size and the variety of skills available, which supports economic growth rather than simply displacing native workers. Immigrants are complementary to native workers in many sectors: they take jobs in construction, agriculture, child care, and elder care, enabling firms to expand and hire Americans for supervisory, accounting, sales, and technical roles. The “one job” theory is misleading because economies are dynamic; immigrant labor can generate additional demand, investment, and entrepreneurship. High-skilled immigrants are especially valuable because they raise productivity and innovation, which in turn lifts wages across the economy. Short-run losses may occur for some low-educated, older native workers directly competing with immigrants, but the aggregate evidence does not show a large net negative employment effect. Immigration’s effect on wages is more nuanced than simple supply-and-demand because firms adjust by investing and hiring more, and native workers shift into different roles over time. On fiscal impacts, highly educated immigrants often contribute more in taxes than they consume in benefits, and many undocumented workers also pay taxes while being ineligible for most welfare programs. Political opposition often reflects broader economic insecurity, housing strain, and cultural concerns rather than immigration itself being the main cause of wage stagnation. Historical anti-immigration waves in the U.S. show that current tensions are not unprecedented and should be interpreted with context. Policy solutions should account for the reality that millions of undocumented immigrants have been embedded in the economy for years, making mass removal economically disruptive.

Data Points: Foreign-born population in the U.S.: 42.4 million - Pew Research Center estimate for 2014; described as a record level. Share of U.S. population that is foreign-born: 14% - Approximate share of immigrants in the U.S. population. Unauthorized immigrant population peak: 12.2 million - Peak level reached before leveling off and declining slightly. Unauthorized immigrant population current level: 11.2 million - Approximate current level at the time of the episode. Share of foreign-born population that is unauthorized: about 25% - Unauthorized immigrants as a quarter of the overall foreign-born population. Foreign-born persons in U.S. labor force: 26.3 million - Last year’s estimate cited in the discussion. Share of total labor force that is foreign-born: 17% - Foreign-born workers as a portion of the U.S. labor force. Immigrant inflow to the U.S.: about 700,000 per year - Average annual immigrant inflow cited as a slow, regulated flow. Immigrant inflow as share of labor force: 0.5% - Annual immigration flow relative to the U.S. labor force. Timing of unauthorized immigrant inflow surge: 1990s to early 2000s - Peri says the issue was most acute then, and has since leveled off or turned negative. Policy window for U.S. legal high-skill immigration: since the 1990s - H-1B visa program cited as enabling high-skilled immigration. Immigration adjustment horizon: 5–10 years - Peri says labor markets adjust over this time frame. Historical anti-immigration period: 1910s and 1920s - Used as a comparison to current backlash.

Pivotal Quotes: "The fallacy that there is one job and if it's taken by immigrant is not taken by native is a fallacy because the number of jobs is not fixed in an economy." — Giovanni Peri: He explains why immigrant labor can create additional jobs rather than merely replace native workers. "Immigration is the most regulated and restricted flow in on Earth." — Giovanni Peri: He emphasizes that modern immigration is already tightly controlled, contrary to popular perceptions. "The disruption of sending them back on the American economy will be so massive that I would say no reasonable person can see such a huge, even just economic cost." — Giovanni Peri: He argues against mass removal of long-settled undocumented immigrants.

Implications: The episode suggests immigration policy should be judged by evidence, not fear: immigration usually raises growth and productivity, while blunt restrictions can harm businesses, consumers, and long-settled communities. The real challenge is managing adjustment and legalization pragmatically.
