In a recent CBS News interview, incoming “border czar” Tom Homan was confronted with the question of whether the benefits of mass-deporting millions of undocumented immigrants were worth the cost. He responded with a question of his own, “What price do you put on national security?”

It’s a question that Americans might be asking pretty soon themselves. Is the price of deporting millions of undocumented immigrants worth the cost?

Undocumented immigrants are far less likely to commit crimes than native-born Americans.

During the 2024 presidential campaign, President-elect Donald Trump described crackdowns on illegal immigration as an essential tool for reducing crime, increasing employment and even lowering housing costs. Never mind that undocumented immigrants are far less likely to commit crimes than native-born Americans and that the threat to national security from their presence in the country is minimal at best.

What was omitted from Trump’s anti-immigrant diatribes were the significant economic costs of deporting millions of undocumented immigrants — and the meager benefits.

According to one estimate from the pro-immigration advocacy group American Immigration Council, arresting, detaining and deporting the 13.3 million people who are either in the United States illegally — or are in the country temporarily without legal status — could cost $315 billion.

Trump campaign officials have said they don’t intend to deport every undocumented immigrant in the country immediately. Considering that the U.S. has never deported more than a half-million people in a single year, it would likely be impossible.

However, even deporting 1 million people yearly could cost nearly $90 billion. Apprehending immigrants, detaining them, court procedures and transporting them out of the country makes mass deportation a complicated and costly endeavor. Indeed, the estimated cost of deporting a single undocumented immigrant is estimated to run as high as $13,000.

Trump has said as recently as this week that he wants to enlist the military in his mass deportation plans, but that is easier said than done. Trump will have to jump through various legal hoops to overcome the impediments to using the uniformed military for domestic law enforcement. To achieve his anti-immigration goals, Trump will likely need Congress to authorize billions of dollars in new spending and hire tens of thousands of new government employees.

Let’s suppose, for a moment, that Trump is actually successful at getting the mass deportation project off the ground. In Trump’s words, there can be “no price tag” on such an effort. In reality, there is a price — and it will quickly be felt by American consumers.

To achieve his anti-immigration goals, Trump will likely need Congress to authorize billions of dollars in new spending.

Today, undocumented immigrants represent 5% of the U.S. workforce, and because two-thirds of them are between the ages of 25 and 54 (compared to less than 40% of the U.S.-born population), they are overrepresented in the workforce.

Many undocumented immigrants take on dangerous, menial and low-paying jobs. They are maids and housekeepers, construction laborers and agricultural workers. Indeed, a whopping 45 percent of agricultural workers are undocumented along with 15 percent of construction workers.

If millions of undocumented immigrants are forced to leave the country, these industries will bear the brunt — as will consumers.

Even if they aren’t deported, fear of getting caught up in workplace raids might push some of the undocumented to no longer show up for work. Either way, farms, construction companies and restaurants may find themselves short-staffed and unable to bring on new workers at a time of low unemployment.

Whatever the case, the labor disruptions will almost certainly lead to higher prices on everything from food to housing. And working class Americans — many of whom voted for Trump — will get hit the hardest.

Moreover, if restaurants are losing cooks and busboys and construction companies can’t find laborers, other native-born Americans such as waiters, construction managers, and architects will be directly affected as businesses shut down or take on fewer projects.

In his acceptance speech at the Republican National Convention, Trump said, “Americans are being squeezed out of the labor force, and their jobs are taken.” That’s not really true, since the undocumented often take on jobs that most native-born Americans simply don’t want. If Trump is successful at deporting millions of undocumented workers, his words will be prophetic; tens of thousands of Americans may soon find themselves out of work.

There are other indirect costs that many Americans who voted for mass deportation probably didn’t consider. For example, many undocumented immigrants work in child care. If they are forced to leave the country, the number of women in the labor force could decrease.

Then there are the tax implications. In 2022, undocumented immigrants paid close to $50 billion in federal taxes and nearly $30 billion in state taxes. They also contributed more than $28 billion to Social Security and Medicare (even though they don’t benefit from those programs).

Migrants are also consumers. Removing them from the country means decreased spending, further undermining the economy.

By nearly any appreciable measure, immigration to the United States is a net economic positive, contributing to higher growth, greater productivity and even a reduced budget deficit.

Conversely, mass deportations will almost certainly lead to slower economic growth, increased unemployment and, ironically, higher inflation.

While the economic costs of mass deportation are significant, we cannot ignore the moral and humanitarian costs. Millions of undocumented Americans have native-born American children.

Migrants are also consumers. Removing them from the country means decreased spending, further undermining the economy.

Are Americans prepared to, again, watch parents ripped away from their children simply to fulfill Trump’s campaign promise? There are undocumented immigrants in practically every community in America. They are neighbors, friends, little league dads and soccer moms. Will Americans who voted for Trump be as blasé about the impact of mass deportation when it directly affects those they know personally?

Mass deportation might be popular on the campaign trail but in practice it is a recipe for an immediate and significant political backlash.

As much as many Trump voters say they wanted mass deportation, few seemed to understand or appreciate the ultimate consequences.

In short measure, they’re about to find out.
