Small-Scale Question Sunday for January 21, 2024

Do you have a dumb question that you're kind of embarrassed to ask in the main thread? Is there something you're just not sure about?

This is your opportunity to ask questions. No question too simple or too silly.

Culture war topics are accepted, and proposals for a better intro post are appreciated.

I was discussing US politics with my wife, as one does, and immigration laws came up. I briefly told her about sanctuary cities, and in response she asked why anyone would support that. I had no answer.

I googled a bit and got some very bad answers, so I’m turning to the motte.

Can the motte provide some pro-sanctuary arguments, and some pro-illegal immigration arguments in general? Consider that you’re giving these answers to a none-American from an ethno-state that enforces its immigration laws, and generally frowns on immigration to it from different ethnicities.

some pro-sanctuary arguments

"sanctuary" is a basket of many different policies. Perhaps the easiest to support is that police who are interacting with illegal immigrants who witness and report crimes should be prohibited from assisting with those immigrants' deportation, because otherwise the incentive is for the witnesses to just not report the crimes, and thereby still not get deported, making it harder to catch criminals before they reoffend (including against citizens and legal residents).

some pro-illegal immigration arguments in general

I've long been amused by Milton Friedman's argument:

"...that Mexican immigration, over the border, is a good thing. It’s a good thing for the illegal immigrants. It’s a good thing for the United States. It’s a good thing for the citizens of the country. But, it’s only good so long as its illegal.

That's an interesting paradox to think about. Make it legal and it’s no good. Why? Because as long as it’s illegal the people who come in do not qualify for welfare, they don’t qualify for social security, they don’t qualify for the other myriad of benefits that we pour out from our left pocket to our right pocket. So long as they don’t qualify they migrate to jobs. They take jobs that most residents of this country are unwilling to take. They provide employers with the kind of workers that they cannot get. They’re hard workers, they’re good workers, and they are clearly better off." - Milton Friedman, "What is America" lecture

Though bear in mind, this was the late 70s. Perhaps "do not qualify for ... benefits" was a reasonable blanket claim then, and crime wasn't even worth mentioning because who's going to risk deportation for stepping even slightly out of line? In the 2020s, when illegal immigrants can get free schooling (and then in-state university tuition rates, in dozens of states) for their kids, and sanctuary policies may explicitly prevent deporting many arrestees, the cost-benefit calculations may have more net losers.

Oh, good answer, on both counts. Is the second part something that people actually say out loud, though? Or is it something that they'll think, but then say something else?

Not sure what you mean by "the second part". The "illegal immigration is good so long as it's illegal" theory was part of a public speech originally, and it does sometimes get quoted out loud still, approvingly. The "we now give illegal immigrants a myriad of benefits" caveat is a common anti-immigration complaint, but I don't know if I've ever seen it specifically pointed out as making Friedman's argument obsolete; it's just pointed out as a general cost of both legal and illegal immigration. The pro-immigration side of that branch of the argument is just attempts to rebut it. E.g. in-state university tuition rates for DACA recipients might make sense economically if you consider DACA-to-legal-citizenship as a fait accompli; if they're not going anywhere either way then in the long run you might get more state taxes out of them as college graduates, even looking at NPV minus tuition subsidies.

By "the second part" I referred to "illegal immigration is good so long as it's illegal", as you inferred correctly. I'm just having a hard time imagining the modal pro-immigrant activist saying something like that, and in effect admitting that they're in support of a tiered system of citizens and non-citizens, where the former live the good life and the latter do the dirty work. It sounds like a very Motte-y argument, and I don't encounter those much in the wild.

It's very much a heavily libertarian pro-immigration argument; the modal pro-immigration activist is a left-winger who would be utterly horrified by it.

Even before the premises about welfare for illegal immigrants became dubious, the biggest sympathetic argument against Friedman was that this sort of "tiered system" was politically unsustainable in the US. Popular morality here includes a big mixture of Newtonian ethics and the Copenhagen Interpretation, so it doesn't matter how happy it makes utilitarians to see starving foreigners upgraded to much-less-impoverished guest workers, they'll be outnumbered by voters who see starving foreigners as someone else's tragedy but welfareless voteless guest workers as unconscionable apartheid.

The modal left-winger's main pro-illegal-immigration argument is much simpler: the immigrants will suffer much less in America than they do at home, and suffering is bad, so they should all get to come to America. It's a very compelling argument when you look at just the first-order effects, I have to admit. But there are a lot of both positive and negative second-order effects, and whether any of those make this idea unsustainable in some way is a more complicated question.
