The economic risk of Trump's deportation plan

Many Americans don’t want them here. But we might miss them if they’re gone.

The surge of migrants entering the United States during part of Joe Biden’s presidency has played to Donald Trump’s signature issue. Trump launched his first campaign for president in 2015 with an anti-immigrant rant, and the issue has worked for him ever since. So Trump, in his third campaign for president, has raised his bid on the issue, promising the “mass deportation” of up to 20 million people if he wins a second term.

Careful what you wish for, America-firsters. If Trump accomplished even part of this plan, it would leave many industries short of workers, raise costs for businesses and consumers, and dent federal tax revenue. That’s not a defense of illegal immigration. Instead, it’s an acknowledgment of the key role migrants play in the US economy despite many Americans’ legitimate concerns about a broken immigration system that generates chaos.

Migration is poorly understood, so first, some basics. Around 1 million people migrate legally to the United States each year, and another million or some come as temporary “guest workers” needed to fill a variety of jobs in agriculture, technology, and other sectors. Aside from the COVID years, those numbers are fairly steady and not especially controversial.

Migrants sneaking into the United States illegally and others who get temporary asylum status are the ones Trump and his followers get fired up about. The number of migrants showing up to seek asylum hit a record high last December — but has since plunged by 57%. In June, President Biden changed US policy, making it much harder to qualify for asylum. At the same time, the United States has been working with Mexico to prevent Latin American migrants from getting to the US border in the first place. If these policies had been in place for Biden’s entire presidency, the surge in 2022 and 2023 wouldn’t have happened and the issue would probably be far less explosive today.

The latest Pew Research data shows that at the beginning of 2022, there were about 11 million undocumented migrants in the United States. Some snuck in. Others overstayed work visas that expired, or failed to show up for hearings meant to determine if their asylum claims were valid. The number is probably higher now, though it’s obviously hard to count people who don’t want to be counted.

Collectively, undocumented migrants are a potent economic force. New research by the Institute on Taxation and Economic Policy finds that undocumented migrants paid $96.7 billion in federal, state, and local taxes in 2022, so the figure would presumably be higher now if there are, in fact, more such migrants in the country. Of that amount, $60 billion went to the federal government, mostly as income and payroll taxes, while the rest went to states and cities.
