Immigration is a complex issue, without a doubt. Many of the questions related to it are economic, and thus highly debatable. Neither the side favoring reduced immigration levels nor the side favoring high immigration levels can agree on the basic facts involved. Even a relatively straighforward question such as, "Are immigrants a net drain on the economy?" is contentious.
For my money, the immigration restrictionists have the better argument on strictly economic grounds. If immigrants contribute to the economy, they don't contribute much. The vast majority of today's immigrants are poor and unskilled. The bottom 50% of taxpayers pay less than 4% of the income taxes, and their share of Social Security and Medicaid taxes is similarly small. Against this must be balanced the huge social costs of immigration: educating children; providing care for elderly relatives who are "imported" after a legal immigrant establishes his residency; the high crime rates associated with many immigrant communities, etc.
Despite this evidence, the U.S. Conference of Catholic Bishops argues flatly that Mexican immigration in particular is a boon to the American economy. In "Strangers No Longer: Together on the Journey of Hope," the USCCB, in conjunction with the Mexican bishops, states that "the United States needs Mexican laborers to maintain a healthy economy." Why? The paragraph does not say.
Another USCCB policy paper, written to buttress the case for legalizing illegal immigrants, inadvertently blows away that factoid: "Undocumented immigrants from Mexico alone contributed between $154 billion and $220 billion to the Gross Domestic Product of the United States in 2000." Let's accept that higher number, and inflate it to $250 billion to account for inflation and additional illegals. This year, the U.S. will have a $12,000 billion economy (see table 1.1.5), so they contribute about 2% of the GDP. By way of comparison, the Federal Reserve Board expects GDP to grow 3.5 to 4% this year. So this vital segment of the American economy, in strictly economic terms, is equivalent to perhaps six or eight months of decent growth.
You may object that people are not cold statistics, and that it is inhuman to consider them as such. Very true, but it is expedient to demolish the pragmatic argument first, so we can clarify the issue (and I would also point out that the USCCB is the one making the utilitarian case, not me.) If high-immigration apologists would make a straightforward moral argument, we would not have to get into pragmatics. Of course, the USCCB does make that moral argument, though these two paragraphs of theirs are irreconcilable:
II. Persons have the right to migrate to support themselves and their families.If something is a "right," it is something to which a person is entitled regardless of the circumstance. In that respect, how can there be a "right to migrate," that is, the right to cross national borders, if nations have the "right to control their borders"? Which right trumps which?
35. The Church recognizes that all the goods of the earth belong to all people.
When persons cannot find employment in their country of origin to support themselves and their families, they have a right to find work elsewhere in order to survive. Sovereign nations should provide ways to accommodate this right.III. Sovereign nations have the right to control their borders.
36. The Church recognizes the right of sovereign nations to control their territories but rejects such control when it is exerted merely for the purpose of acquiring additional wealth. More powerful economic nations, which have the ability to protect and feed their residents, have a stronger obligation to accommodate migration flows.
If you read the documents and position papers of the USCCB, you come to the inescapable conclusion that they do not regard illegal immigration to be a "real" crime. Indeed, you come away with the impression that people should be allowed to travel, reside, and work wherever they want, and with no restrictions. Anyone who thinks differently is in need of conversion:
Faith in the presence of Christ in the migrant leads to a conversion of mind and heart, which leads to a renewed spirit of communion and to the building of structures of solidarity to accompany the migrant. Part of the process of conversion of mind and heart deals with confronting attitudes of cultural superiority, indifference, and racism; accepting migrants not as foreboding aliens, terrorists, or economic threats, but rather as persons with dignity and rights, revealing the presence of Christ; and recognizing migrants as bearers of deep cultural values and rich faith traditions.I solemnly disagree with the USCCB's esteemed bureacrats on this one. I believe that all immigration should be drastically curtailed by 80-90%, and this belief does not spring from "cultural superiority, indifference, [or] racism." Rather, I object to high immigration levels precisely because it is socially unjust to allow it.
States have a prior moral duty to their citizens. That's their place in God's temporary plan for us, until Christ comes to reign in glory and then we won't need states anymore. In the meantime, the world is divided into polities that are supposed to protect their citizens from harm, and provide an environment for them to flourish.
The Church teaches that states (and we) ought to consider the effects of a given action on the poor, before enacting any law connected with economics. This is called the "preferential option for the poor." We can thus see that in the Catholic scheme of things, states take care of their people, and should care particularly for the poor and the most vulnerable.
High immigration levels hurt the poor and the vulnerable, and are thus immoral. How do they do that? Through supply and demand: immigrants, legal or illegal, flood certain parts of the labor market, driving down the price of labor. Businesses love that, but it ends up screwing over the people who were already in the U.S., including less recent immigrants. If these labor market segments were more static, businesses would be forced to train these workers, give them better equipment, and pay them more.
High immigration levels not only hurt the poor and the vulnerable in the U.S., but also in Mexico and other countries, too. It allows underdeveloped nations to ship their "surplus" population abroad, instead of dealing with their own faulty economies.
Illegal immigration fosters disrespect for the law, but even legal immigration keeps poor people poor. How can the bishops' conference possibly support such a harmful thing?
