Alright, had I not be so overwrought from events yesterday, I might have written a more sedate and nuanced OP, so here are some points I’d like to add, which will also cover some of the responses:
There are three main reasons for not wanting “open borders”:
1. Not wanting to be unsafe
The desire to keep out criminals and other bad actors from one’s territory is perfectly fine in my view. No country has ever wanted this, even if they didn’t otherwise feel the need to control migration, so I don’t think it’s particularly germane to the debate we’ve traditionally had in the US. Though, of course, Republicans have always portrayed Democrats as being lax in this regard.
2. Not wanting to share
This is the most important of the three reasons in the US. We don’t want poor Mexicans coming into the country because we don’t want to share what we have with them. Even if they are adding to the economy, we fear that they are taking more than they are giving. As I said in the OP, however, we are schizophrenic with respect to this reason: big business, which the GOP seeks to support, requires the labor of the undocumented in order to function, but then the same GOP rails about the “illegals.” So which is it? It’s both, since consistency means nothing to the GOP, and not knowing one’s own mind in this case is politically expedient. It’s also economically expedient, as well as exploitative and oppressive, since poor Mexicans are treated as expendable guest workers. In short, our immigration system is deplorable, but it won’t change until ethics win over exploitation.
This motive for not wanting immigration can get a bit complicated. Do I want Mad Emperor Trump to invade Greenland and take all their resources? Absolutely not. But do I think it’s cool that 50,000 and change Greenlanders get to sit on all that land and get all its value and all its space for themselves just because it’s “theirs”? Well, not really!
Now wait, before you get mad, let’s look at it from another angle. The Greenlanders are highly sympathetic: they’re cute, civilized, modern, and basically Western in culture (yes, I know they are also native to their land to a large extent–but still).
Yet not all people who sit on valuable land are sympathetic. Is it a good thing that a bunch of Saudi princes sat on a bunch of oil, took it all for themselves, and formed a despotic country that exploits a very large number of guest workers? I think you’ll see my point, even if you don’t totally vibe with what I’m saying.
What I’m not saying is that there is a cut and dried solution for any of this.
3. Not wanting to be diluted
In the US, white supremacists don’t want to see Hispanics or brown people in general become a majority. In the US context, this is an unacceptable reason to reject immigrants, especially if we are exploiting them anyway per above.
But is it unacceptable in every context? That’s complicated. In the US, we are used to the traditional melting pot ideal, which held that anyone can come here if they learn English (more or less) and adopt the culture (more or less). To our credit, we have been very good (but of course not perfect) at welcoming people from all around the world and having everyone get along (more or less–obviously this is a simplification).
Not every culture, however, is “designed” to be a melting pot. For example, I’m a Japanese/English interpreter, and I lived in Japan for eight years. Japan is the polar opposite of a melting pot, and welcoming too many immigrants (though they dearly need the labor and population boost at this point) would easily wipe out the language and (therefore) the culture.
I like the fact that there are different cultures in the world. Heck, English is already endangering local languages in multiple countries without any imperialist aggression.
Again, I’m not saying there is any solution.
Finally, I don’t think we need a World Government right now just to prove we could do it. It would be extreme folly, for an exmple for the US to try to merge with China. It would just be dumb.
So I’m not a utopian. I don’t think I’m naive about the issues. But I also think that we in the US should not be in denial about the dark side of our motivations, and neither should we toss around the term “open borders” without understanding its connection to our motivations, whether positive or negative.
