In 1960, one paycheck from a factory job could support a family of five. The worker owned his house and retired with a pension. A single income was enough to reach the middle class, and for most families it was the norm.[4]
Sixty-five years later, that arrangement is gone. Two incomes are the baseline for a middle-class household, and in the most expensive metros two incomes still fall short. The change has many causes. One of them is that the American worker now competes in a labor pool nearly two and a half times larger, and a far larger share of it arrived from abroad.
The Pool Grew Faster Than the Country
In 1960, the civilian labor force numbered about 70 million. By 2024 it had grown to about 168 million.[3] The population grew over the same period, but the labor force grew faster, and immigration supplied much of the difference. Since 1990 alone, the country added roughly 32 million foreign-born residents.[9]
In 1970, the foreign-born were 4.7% of the U.S. population, the lowest share on record.[2] By 2024, the foreign-born were 19.2% of the labor force, nearly one worker in five.[1] Immigrants cluster in the working ages, so their share of the workforce runs higher than their share of the population. A worker who competed against a nearly all native-born pool in 1960 now competes against one in which almost a fifth of the workers were born abroad.
U.S. civilian labor force, 1948-2025
An American competes against 171 million people, not 61 million
In 1948 there were 60.6 million Americans working or looking for work. In 2025 there were 170.8 million. Set against the whole population that is 50 job-seekers per 100 Americans, up from 41 in 1950 and 47 in 1980. The Labor Department has counted the foreign-born separately since 2005, and they were 32.7 million of the 2025 total, up from 22.0 million when the count began.

The labor force counts everyone aged 16 and over who is working or looking for work, and it counts workers here illegally alongside everyone else. The Labor Department did not ask where workers were born until the 1990s and does not publish the split before 2005, which is why the red band starts there. The lower panel divides that labor force by the resident population (Bureau of Economic Analysis) so that growth in the country itself is netted out. Because of the 2025 federal government shutdown, BLS built the 2025 annual averages from eleven months and notes they are not strictly comparable with other years.
A larger labor pool, whatever its makeup, gives employers more room to hold wages down. Every additional worker in a field is another bid for the same jobs.
The clearest way to see how much the competition changed is to count foreign-born workers against American-born ones. In 2005 there were 17 foreign-born workers in the labor force for every 100 born here. In 2025 there are 24.[10] Over those two decades the American-born workforce grew 6.7%, from 127.3 million to 135.8 million. The foreign-born workforce grew 46.4%, from 22.0 million to 32.3 million. Of the 18.8 million people added to the labor force, 10.3 million were born abroad.[10]
Labor force growth by nativity, 2005-2025
The foreign-born workforce grew six times faster
Since 2005 the number of American-born people working or looking for work has risen 8.5%, from 127.3 million to 138.1 million. The number born abroad has risen 48.6%, from 22.0 million to 32.7 million. Both lines start at 100 so the two rates can be compared directly.
Source: U.S. Bureau of Labor Statistics, Current Population Survey, annual averages of the native-born and foreign-born civilian labor force, retrieved from the BLS public data API. Indexing both series to 100 in 2005 compares their growth rates, not their size: the American-born workforce is roughly four times larger throughout, so its slower percentage growth still represents 10.8 million additional workers. Because of the 2025 federal government shutdown, BLS built the 2025 annual averages from eleven months and notes they are not strictly comparable with other years.
Which Jobs Take the Pressure
The competition does not fall evenly across the economy, and the pattern runs opposite to the way the program is usually defended.
Foreign-born workers are 19.2% of everyone employed. In natural resources, construction and maintenance they are 28.5% of the workforce. In service occupations, 24.4%. In production, transportation and material moving, the factory floors and warehouses and truck cabs, 23.9%. In management and professional work, the category that the case for high-skill immigration rests on, they are 16.2%, below their share of the workforce as a whole.[11]
Among men the construction figure is starker still. In 2025, 21.9% of employed foreign-born men worked in natural resources, construction and maintenance, against 14.2% of native-born men.[11]
Foreign-born share of each occupation group, 2025
The competition is heaviest in the jobs that never needed a degree
Foreign-born workers are 19.2% of everyone employed. In construction, maintenance and farm work they are 28.5%. In service jobs, 24.4%. On factory floors, in warehouses and behind the wheel, 23.9%. In management and professional work they are 16.2%, below their share of the workforce as a whole.
Sources: U.S. Bureau of Labor Statistics, Foreign-Born Workers: Labor Force Characteristics, 2025, for how foreign-born and native-born workers are distributed across the five broad occupation groups; Current Population Survey annual averages for employment by nativity, 31.3 million and 132.2 million. The share in each group is the foreign-born count divided by the total, computed from those two published figures. The Labor Department built the 2025 annual averages from eleven months because of the federal government shutdown that October, and notes they are not strictly comparable with other years.
Geography compounds it. The foreign born are 24.5% of the labor force in the West and 22.7% in the Northeast, against 10.8% in the Midwest.[11] A carpenter in Los Angeles and a carpenter in Ohio are not working in the same labor market.
The professional end is not untouched, it is concentrated. USCIS approved 406,348 H-1B petitions in 2025, and 62% of them went into computer-related occupations, with systems analysis and programming alone accounting for half of all approvals.[12] The pressure that spreads thinly across management and professional work as a whole lands hard on one set of desks.
The Leverage Went With It
The single-income era was also the high-wage era. Real wages for the typical worker rose almost without interruption from the mid-1920s through the early 1970s.[6] Median family income roughly doubled between 1947 and 1973, and the gains reached the whole income distribution, not just the top.[5]
The reason was scarcity. That stretch ran inside the 1924-to-1965 immigration restriction. Congress had cut annual admissions about 80% in 1924 and held them low for four decades, and the labor force grew at roughly the native birth rate. When workers are scarce, the employer is the one who has to compete. A plant that needed a hundred more hands could not import them. It had to raise the wage until American workers took the jobs, or watch a competitor hire them first.
That is where the paycheck came from. A worker could walk into a factory knowing the factory needed him more than he needed that particular factory, and the wage reflected it. The scarcity bargained even for workers who never asked for a raise, because the going rate was set by employers bidding against one another for a pool that grew slowly. A growing economy split its gains with the people who produced them, because the people who produced them could not be easily replaced. That leverage is what a single paycheck rested on.
The trend reversed after 1970. Real pay for the typical worker flattened and has barely moved since.[6] The 1965 Hart-Celler Act and the 1990 Immigration Act reopened high-volume admission, and the labor pool began growing far faster than the native birth rate. The employer who needed a hundred more workers now had a deeper pool to draw from, and the pressure to raise wages eased.
The Other Causes
Immigration is not the only reason wages stalled and one income stopped being enough. Millions of women entered the workforce, at first through expanding opportunity and later, for many households, through necessity as one paycheck bought less. Automation replaced factory jobs.
And a large share of the work left the country. Manufacturing employment peaked at 19.4 million in 1979. It was still 17.3 million in 2000. By 2010 it was 11.5 million, a loss of 5.8 million jobs in the decade that followed China's entry into the World Trade Organization. It stands at 12.8 million today, 6.6 million below the peak.[13] The worker who lost one of those jobs did not face a foreign competitor at home. The job itself moved to the competitor.
The two pressures work on the same person from opposite directions. Offshoring removes the jobs that can be done anywhere. Immigration raises the number of bidders for the jobs that cannot, which is why the foreign-born share is highest in construction, food service and delivery, the work that has to be done where the customer is.
Each of those moved wages independently of immigration. Immigration is the one Congress sets directly. Congress cannot legislate away automation or foreign competition. It sets the number of workers admitted each year, and since 1990 it has set that number high.
The Contest Is Not Only for Jobs
The competition reaches past the paycheck, and it does not fall on everyone. In the parts of the country that immigration passed over, a single income still stretches. A worker in a small city in the Midwest or the South, where the population grew slowly and housing kept pace, can still buy a house on one paycheck and raise a family on it. The squeeze is concentrated where the newcomers landed. The 20 metros that took in the most immigrants after 1990 are the same metros where housing pulled out of reach.[9]
Housing is the largest cost a family carries, and it is the one that moved the most. The national home price-to-income ratio rose from about 3.0 in 1990 to 5.6 in 2024.[7] Median rent rose about 28% after inflation over the same period. A house that cost three years of household income now costs almost six.
Cost of a U.S. home, relative to income
A home costs five years of income now, and more where immigration concentrated
Nationally a median home ran about 4x median household income through the 1990s and about 5x today. Across the 109 metros over 500,000 people the ratio rises with a metro's foreign-born share: 3.2x under 5% foreign-born, 4.0x between 5 and 10%, and 5.2x above 10%.
By year, nationally
Median sale price divided by median household income. It held near 4x through the 1990s, then stepped up after 2000 and has not come back down.
By a metro's immigrant share
Across all 109 U.S. metros over 500,000 people, the more foreign-born a metro, the higher its home price-to-income ratio.
By year: median sales price of houses sold (U.S. Census Bureau and HUD, FRED series MSPUS, annual average of the four quarters) divided by median household income (Census Current Population Survey). One consistent basis across every point from 1975 to 2024; nothing is spliced. FRED's income series begins in 1984, so the 1975 and 1980 points are taken from Census Table H-6, which carries the same household series back to 1975. That is as far back as it goes: earlier years exist only for family income, a different and lower basis. By metro: American Community Survey 2024 one-year estimates, median home VALUE divided by median household income across all 109 metros over 500,000 people. Value-based ratios run about a point below sale-price ratios, so a metro reading 5.2x is not directly comparable with the national 5.0x above it.
The worker of 1960 bid for a house against local buyers. The worker of 2025 bids against a metro that added hundreds of thousands of new residents and did not build enough housing to hold prices down. Where that did not happen, in the low-immigration interior, the old arrangement mostly held. Schools, emergency rooms, and entry-level jobs face the same arithmetic. More people competing for a fixed supply raises the price of all of it.
Who Captured the Difference
The economists who study immigration have measured where the money moves. George Borjas of Harvard calculates that immigration produces a small net gain to the economy, about 0.3% of GDP, alongside a large transfer inside it. Roughly $500 billion a year shifts from workers who compete with immigrants to the employers who hire them.[8] The 2017 National Academy of Sciences study found the same pattern.
The $500 billion is not lost to the economy. It moves from the people bidding for jobs to the people hiring for them, which is why the aggregate figure can look small while the effect on any one worker's wage does not.
Cutting the Number Again
The world the worker's grandparents lived in was the product of a policy choice. Congress cut immigration in 1924 and held it low for 41 years, and the American worker held the strongest bargaining position in the country's history. Congress reversed that choice in 1965 and again in 1990.
Congress can cut the number again. Lowering annual admissions and holding them there would slow the growth of the labor pool back toward the native birth rate and return bargaining power to the worker, the same way the 1924 cut did for four decades.
Recommendations
- Replace the Immigration Act of 1990 and cut annual admissions by at least half, toward the pre-1965 level of about 200,000 a year, to slow the growth of the labor pool.
- Replace the H-1B with an exceptional-talent visa capped under 10,000 a year and end the Optional Practical Training program, removing the channels that expand the professional labor supply at below-market wages.
- Narrow family migration to spouses and minor children, ending the chain-driven growth in the workforce.
- Enforce the border and worksite so the legal cut is not undone by illegal hiring, using mandatory E-Verify.
