As I mentioned in my note yesterday, the common argument that immigration is significantly costly through welfare is mostly empirically falsified. The fact of the matter is immigrants usually aren’t qualified for such programs, illegal immigrants mostly cannot and do not receive them, and immigrants as a whole wind up contributing more to the government’s balance sheet through economic growth and tax receipts than they take through welfare transfer payments.

However, there is one fact I neglected to mention yesterday worthy of its own post: if those opposed to immigration on the grounds of welfare costs were really sincere in that argument, they also need to consider the fiscal costs of enforcing their beloved immigration laws. As the New York Times editorial board pointed out yesterday, these costs are not insignificant:

The Migration Policy Institute reported in 2013 that the federal government spends more each year on immigration enforcement–through Immigration and Customs Enforcement and the Border Patrol–then on all other federal law enforcement agencies combined. The total has risen to more than $19 billion a year, and more than $306 billion in all since 1986, measured in 2016 dollars. This exceeds the sum of all spending for the Federal Bureau of Investigation; the Drug Enforcement Administration; the Secret Service; the Marshals Service; and the Bureau of Alcohol, Tobacco, Firearms, and Explosives.

These fiscal costs get worse when you consider that Donald Trump wants to expand ICE’s budget even further and, of course, the $8-$12 billion dollar wall.

Further, if you are a civil liberties type concerned with the social and fiscal costs of mass incarceration, immigration enforcement looks even bleaker:

ICE and the Border Patrol already refer more cases for federal prosecution than the entire Justice Department, and the number of people they detain each year (more than 400,000) is greater than the number of inmates being held by the Federal Bureau of Prisons for all other federal crimes.

The war on immigrants makes the war on drugs look tame.

Of course, these costs are pretty small when compared to the welfare state, but immigrants are not the ones driving up those welfare costs and they might even reduce it with more tax receipts. The truth is that furthering immigration restrictions and enforcement is truly fiscally irresponsible, not respecting the right to freedom of movement and contract.
