I was listening to Batya Ungar-Sargon on the Fifth Column the other day and realized we had fundamentally different models of how the modern American economy works. This post is exploration of how I think we ought to model the economy without much math.
Batya’s argument against immigration is that an influx of foreign workers increases the supply of labor, thereby driving down wages of the people already here. Her position singles out low-wage workers, suggesting that illegal immigrants take jobs from low-skilled domestic laborers, depressing their wages. However, this view is problematic for several reasons and fails to account for the nuances of the modern American economy.
First, as a side note, we could prioritize an immigration policy that tries to attract highly skilled instead of low-skilled workers! The Institute for Progress has a whole interactive tool on how to do this. But the last time there was a Republican President, Trump actually reduced legal high skilled immigration.
But more importantly, the American economy is not a fixed pie where low-skilled immigrants simply compete with Americans for a limited number of jobs. Consider a worker from Honduras. In their home country, employment opportunities may be limited, with jobs primarily in agriculture, local services, or perhaps managing a hotel catering to foreign tourists. However, if that same worker were to immigrate to the United States, their productivity would increase significantly, even if performing the same job.
The United States is an advanced, technologically sophisticated economy with a vast accumulation of capital and expertise across various sectors. By operating within this economic environment, workers gain access to cutting-edge technology, sophisticated management systems, and an abundance of resources that enhance their productivity. For instance, a hotel manager in the United States would likely oversee operations catering to business clients from major corporations, leveraging management software, efficient business processes, and integrated systems to optimize efficiency and service quality. Most American hotels require very few people to run them because there is so much automation already deployed. The same worker, performing the same role but within the context of the American economy, would become exponentially more productive due to the surrounding technological infrastructure and capital resources.
This phenomenon is not limited to the hospitality industry; it extends across the entire economy. The United States is a knowledge-based, service-oriented economy, where workers can be highly productive by leveraging the accumulated expertise, human capital, and technological advancements embedded within American companies and institutions.
You can see this dynamic if you take the Cobb-Douglas production function, which is a fairly simple model of outputs as a function of labor (L), Capital (K), and total factor productivity (A):
Total Factor Productivity or TFP represents technology, knowledge, and accumulated innovation that isn’t directly attributable to adding more labor or machines and buildings. In the US, TFP and capital components of this function are remarkably high, suggesting that the economy is labor-constrained. Adding even a small amount of labor can lead to substantial increases in productivity due to the abundance of capital and technological resources available.
And we see this concretely in the fact that Americans are paid so highly. Immigrants come to the US and see massive pay raises because they are now embedded in a economy with highly advanced knowledge, processes, technology, and automation. The American economy is adept at integrating labor and equipping workers with the knowledge and tools necessary to become highly productive contributors.
Furthermore, immigrants not only contribute to the labor supply but also represent a source of consumer demand. By purchasing housing, goods, and services, they stimulate economic activity and create opportunities for further businesses and workers across various sectors. Immigrants need to buy houses, groceries, haircuts, and cars too.
Of course, that doesn’t mean we should necessarily just throw open the gates to all immigration immediately; the fact that there are large benefits does not mean there are no costs. It takes time for new workers to be integrated into any economy and for their spending to be accounted for in new supply for everything they are buying. If new workers are concentrated in a specific industry, it can take time for that industry to expand to accommodate the new labor market. Thus, we can suggest specific policies that would lessen immigration impacts that are concentrated on specific people or industries.
For example, we should make the labor market as dynamic as possible. Hiring and firing should be relatively easy. Public sector unions that protect poor performers make it their services worse and make it harder to higher good talent. Also, healthcare should not be tied to your job. This would make any specific job relationship less critical for workers since switching jobs doesn’t mean switching providers. It also reduces the cost and overhead for employers to hire new workers, especially for low wage workers where healthcare would be a significant fraction of total compensation. We can also have regulations that require immigrants to live in different areas of the country. The US is a vast economy with 54 metro areas with over a million people, and over a 100 with populations over 500,000. That’s a lot of local economies we could spread immigrants out over to avoid huge shocks to the housing markets if immigrants concentrated on specific cities. As far as specific industries, many other countries have specific point based systems to target immigrants with key skills. The U.S. largely does not do this, and we ought to.
In summary, the belief that immigrants depress wages and displace native workers is the result of a direct failure to understand fundamentally the dynamic and efficiency of the American economy. The United States is a highly advanced, knowledge-based economy that can effectively leverage additional labor by integrating it with its vast capital resources and technological sophistication. Rather than viewing immigration as a threat to the working class, it should be recognized as a potential source of economic growth and productivity enhancement, particularly in a labor-constrained environment. When there are drawbacks, our goal is to figure out how best to minimize them in order to fuel the economy and make America grow.
