> So a country looking to the well-being of its own people first, and only second to the well-being of others, is morally indefensible?

In the context of an argument arguing that there aren't enough jobs to go around because immigration is too high, your notion of a government's "own people" is nativist, because actually legal immigrants are also the government's "own people". Certainly this is the case for legal immigrant citizens. Legal immigrant non-citizens may not be full participants in a country's democracy, their right to live and work in the country may be revocable, and the government may not answer to legal immigrant non-citizens in a democratic sense, but they are otherwise full participants in society - they use the same infrastructure, buy the same goods and services, and can be communal forces for good or bad, just like anybody else in society. So yes, they are the government's "own people", and when the government acts on a societal-wide scale (taxes, infrastructure spending, etc.), it does so in a way which affects all of us.

Illegal/undocumented immigration is a black hole of a topic that more often than not devolves more into a discussion about the rule of law vs. realpolitik than it does about whether immigration quotas are good or bad. In any case, the government's de facto inability to enforce immigration quotas has absolutely nothing to do with the question of whether immigration affects the ability of legal residents and citizens to find high-paying work, since virtually no illegal/undocumented immigrants can find high-paying work.

You're arguing about who counts as a country's "own people", and in the sibling comment, whether limiting immigration is in the interest of those people.

In my comment, I raised neither point.

You are not addressing whether a country prioritizing it's own people is morally defensible - the core point of my comment.
