Certain people really talk about that like you say - but your question is about healthcare and not social benefits.
Yes, because it is a fact that can't be skirted. If you have limited resources, i.e. because the world is divided into nation-states, then no nation state can provide benefits to everyone in the world who needs them unless there is a global economic culture that is so sustainable and affordable that anyone can migrate anywhere without putting undue economic burden on the government and people where they go.
So, if people could migrate to Scandinavia, for example, without requiring energy for heating, energy/money for importing food, money for health care and other needs, then what would be the problem with moving there? It could be fun and interesting to learn new language and culture, etc. For that to be possible, however, there have to be universally-available resources, e.g. because there is a global market for, say, generic drugs that cost the same everywhere. That way, whether you are in Europe or Africa or South America or North America or Asia or wherever, you can get the medicine and care you need without burdening others.
And if you're talking about designing a system of care and benefits that doesn't burden others, you are talking about eliminating socialism and replacing it with a totally-inclusive free market; i.e. a free market where access to work and purchasing power is unlimited for all the commodities that are necessary for basic living.
So when people in the US are calling for socialized healthcare and/or other welfare benefits, they are implicitly calling for non-citizens to be excluded; and thus for a wall. If they didn't want a wall, they would support a de-socialized free market system where healthcare and everything else that welfare states provide are achievable without government intervention, and then non-citizens would be free to participate in that economy and achieve their own healthcare, etc. with their own effort/labor/productivity.
