Who supports "open borders" and what do they support exactly?
IIRC, the US-Mexico border was never open, but it was quite porous. People would come to the US, work for a season to make some money, then go home.
Then once border security started to be tightened, leaving was too risky so people would stay leading to a huge increase in the number of undocumented people living in the US.
I think there's probably some leftist argument against this system on account of how we're taking advantage of poor countries and something something workers rights, but I think removing the ability to leave, to go home is the worst of both worlds.
They run counter to the notion of sovereignty and local agency which we value greatly in the US
The irrationality of strict country borders and heavy migration controls will emerge as a heavy global challenge due to economic and climate migration and aging populations
I don't think we have a good answer for what replaces them, but I don't believe there's enough evidence to state that hasty decisions made after WWI and WWII should forever govern global human freedoms - and we need a better approach than war to renegotiate some of this
For example the Bible defined borders of "The Land of Israel" which are still fought over today: https://www.biblica.com/bible/?osis=niv:Ezekiel%2047:13%E2%8...
The "Eternal Treaty" between the Hittites and Egyptians defined spheres of influence and position of various cities
The Peace of Antalcidas defined the border between Greek and Persian influence and assigned various cities to different powers: https://en.wikipedia.org/wiki/Peace_of_Antalcidas#Effects
One of the biggest drivers of strict borders was tax collection: they defined who could collect tax from which subjects. This was a common source of conflict and so anywhere feudalism was practiced strong border definitions were strongly enforced.
It's possible the grandparent is talking more about the idea of limiting travel across those borders. That is a more defensible position but even then it was more about the the costs of enforcement.
Trade routes had very strong border enforcement because the borders were places taxes were collected for example, and there were limits on who could travel various routes.
For example Venice, Genoa and the Ottoman Empire jealously protected European end of trade routes linking to the spice road.
It's a very prevalent idea among US immigration activists and left-leaning people.
> what do they support exactly
Generally speaking, that people can move anywhere, if they want to. This article/interview/book covers it in more depth:
It doesn't show up in the short term numbers because it is a long-term solution. But Americans aren't interested in long-term solutions.
One could easily argue that Trump made for more progress as far as the immigration courts being backed up by simply not having an almost completely open border like we did with Biden.
Look at the huge jump due to his policies: https://www.economist.com/content-assets/images/20240127_EPC...
The same was not true for Obama, who was actually much better than Bush.

(Also, FWIW, those immigration surges were good things (for the US), and likely helped the US stick the "soft landing" instead of slipping into a post-covid recession)
Trump: "Border is closed. We're deporting people, starting with mostly those that have committed serious crimes."
How did it do that?
The main point is that Biden acted like his hands were tied and Trump showed that they clearly weren't, and that we already had the tools to effectively shut down illegal immigration (through the border, at least).
The in-effectivity was due entirely and directly to Trump interfering in the matter. How can a president sign legislation that doesn't reach his desk because the party in control of the legislative body is in the pocket of a man who cares more about his career than the nation's well-being?
> Allow workers to freely migrate between countries to seek employment without restrictive immigration controls. Demilitarize the border, end all immigrant detention and deportations, immediate amnesty for all immigrants regardless of current immigration status, and provide access to jobs, labor rights, and social services to all immigrants.
Note they say “to seek employment” and “without restrictive border controls”, not “for any purpose” and “without border controls”. This does not mean they’re advocating to let in convicted murderers or people who just want to migrate for welfare benefits. Calling it “open borders” is an exaggeration in absolute terms, though it is for sure accurate as a relative comparison to what we have now.
Also, their political party, as such, is the Democrats. DSA is not a political party. But yeah they are members of DSA as well as being Democrats.
