How Would Mass Deportations Affect the US Economy?

Donald Trump has promised to conduct “the largest deportation effort in American history,” no matter what it costs—but the price tag may be bigger than expected. In today's video we look at a history of US border control and the economic costs of deporting more than six percent of the US workfo

Episode Summary

Executive Summary: The podcast examines immigration as a major 2024 political and economic issue, focusing on U.S. border policy under Biden and Trump, the mechanics of asylum and deportation, and the likely costs of mass removals. It argues that large-scale deportations would be extremely expensive, legally complex, and disruptive to labor markets, prices, growth, and communities.

Main Topics: Immigration as a voter issue in 2024 (Priority: 5/5): The episode opens with polling showing immigration became a top concern in the U.S. and Europe, framing the topic as politically central and emotionally charged. U.S. border flows, asylum, and enforcement changes (Priority: 5/5): It explains that the border is not 'open,' but that policy changes under Biden, court rulings, pandemic-era restrictions, and asylum backlogs altered migrant behavior and crossing patterns. Trump's deportation and immigration agenda (Priority: 5/5): The discussion covers Trump’s plans for mass deportations, tighter visa rules, birthright citizenship changes, and the practical dependence of those plans on Congress, funding, and courts. Economic effects of deportation (Priority: 5/5): The episode argues that removing millions of workers would shrink output, raise labor shortages, increase inflation, and damage sectors like agriculture, construction, and caregiving. Fiscal and administrative feasibility (Priority: 4/5): It highlights the scale of detention, staffing, judges, flights, and funding needed to deport millions, showing that the operation would be far larger than current enforcement capacity. Historical and comparative context (Priority: 3/5): The speaker compares current proposals with previous U.S. immigration policy, older restrictive laws, and European/British labor market experiences to show that migration shocks reshape economies.

Key Arguments: Immigration is politically salient because many voters now favor lower immigration and view border control as a priority. The U.S. border is not literally open; higher crossings reflect enforcement choices, asylum procedures, court backlogs, and migrant incentives. Migrant flows rose because asylum seekers could surrender at the border, stay pending hearings, and eventually obtain work authorization. Mass deportations are operationally difficult: they require large detention capacity, many more officers and judges, and expensive transport and processing. Economic theory and evidence suggest unauthorized immigrants are not perfect substitutes for U.S.-born workers; removing them can reduce business activity and also eliminate local demand. Deportations would likely raise prices in labor-intensive sectors such as food production, construction, childcare, and household services. The expected macroeconomic effects include lower GDP, lower capital returns, weaker investment, and higher inflation, although trade balance may improve through a weaker dollar. Most undocumented immigrants are embedded in U.S. communities, and deportation would affect millions of children and long-settled households. Trump’s broader agenda, including birthright citizenship changes, faces major constitutional and legal obstacles and likely cannot be done by executive order alone. Politically, Trump may be constrained by the stock market, legal challenges, congressional funding limits, and the high real-world cost of his promises.

Data Points: U.S. foreign-born share of population: 14.3% - Census Bureau estimate of immigrants as a share of the U.S. population Foreign-born population by origin: Mexico: 23% of total immigrant population - Largest immigrant origin group in the U.S. as of 2022 Foreign-born population by origin: India: 6% of total immigrant population - Second-largest highlighted origin group Foreign-born population by origin: China: 5% of total immigrant population - Third-largest highlighted origin group Foreign-born population by origin: Philippines: 4% of total immigrant population - Another major immigrant origin group Estimated illegal immigrants in the U.S.: 11 million to 13 million - Approximate size of the undocumented population Illegal immigrants in the U.S. workforce: 8 million to 10 million - Estimated undocumented workers, described as up to 6% of the U.S. workforce Share of U.S. workforce: Up to 6% - Approximate share represented by undocumented workers Concentration in four states: Nearly half - Many undocumented immigrants live in California, Florida, New York, and Texas CBP apprehensions at southern border in 2022: Almost 2.5 million - Record high illegal crossings after pandemic border restrictions eased Trump first-term deportations: 1.2 million - Total deportations during Trump's first term Obama deportations: More than 3 million - More than either Clinton or Bush, according to the transcript Pandemic asylum rule delay: At least 180 days - Time before some asylum applicants can apply for work permits Court backlog timing: Up to 7 years - Time it can take for asylum cases to be decided Immigration court backlog: 3.7 million cases - Pending cases before U.S. immigration judges Immigration judges: 735 judges - Current number of U.S. immigration judges referenced Detention beds Trump border czar said would be needed: 100,000 additional beds - Estimate for processing deportations Detention capacity estimate: 24 times current capacity - American Immigration Council estimate to deport 1 million immigrants per year New enforcement officers needed: Around 30,000 - AIC estimate for 1 million deportations annually Average removal flight cost: About $17,000 an hour - ICE testimony to Congress in 2023 Estimated cost of mass deportations: Around $1 trillion - Projected cost of deporting millions at scale Estimated time for mass deportations: At least 10 years - Timeframe suggested for carrying out the operation Taxes paid by undocumented immigrants: Just under $100 billion per year - Federal, state, and local taxes contributed by undocumented immigrants Unauthorized immigrant share of farm workers: About 1 million of 2.5 million - UC Davis estimate of U.S. agricultural labor reliance Unauthorized immigrants in construction: 1.5 million - Number working in construction, a sector harder to automate GDP impact of removing 1.3 million workers: -1.2% - Warwick McKibbin model estimate GDP impact of removing 7.5 million workers: -7.4% - Warwick McKibbin model estimate Undocumented immigrants living in U.S. over a decade: Nearly 80% - Pew Research figure showing deep community integration American schoolchildren with at least one unauthorized parent: 6% - Estimated share of schoolchildren affected by deportations Children affected by deportations: 4.4 million - Number of American children potentially impacted Public support for allowing undocumented immigrants to stay: Roughly 60% - Share of American voters favoring legal status or work visas

Pivotal Quotes: "Now that Trump is planning to deport millions of illegal immigrants, they're saying that this will cause labour shortages, increasing wages and inflation. She asks in her article, how can both of these claims be true?" — Host: Summarizing the apparent contradiction between anti-immigration wage arguments and inflationary concerns "There is, of course, not an open border." — Host: Clarifying that migration levels reflect enforcement and policy, not the absence of laws "The worst first, meaning migrants who are in the country illegally and have been convicted of crimes." — Tom Holman: Describing the stated priority for deportations under a Trump administration

Implications: Mass deportation would be expensive, slow, and economically disruptive, likely raising prices and shrinking output in labor-dependent sectors. Immigration policy will remain constrained by courts, Congress, and the labor needs of an aging U.S. economy.
