At any rate, I do think some clarity has developed. I am much less inclined toward open borders.
There is a strictly quantitative question here too. If Europe and the US really did open their boarders, how many people would actually come? And what does one mean by "open boarders".
America seems to believe that approximately the whole population of Mexico is desperate to relocate to america, but I imagine that not even nearly true. I expect that it would follow the pattern of the European Union Enlargement, where, it was feared, a large number of eastern europeans would sweep into richer states. In fact, less than 2% of the population took advantage, and they were disproportionately young highly skilled graduates or tradesmen. It has created something of a stereotype of the Polish Plumber in the UK, but at the time, which many people forget, good plumbers where in short supply in the UK and were earning a lot of money (
there were reports of university lecturers quitting to become plumbers). And then, in a little reported phenomenon, many of them returned to Poland after doing 3-7 years in the UK. Its hard to permanently settle down in a new culture, and most people don't want to.
Its different when a country is war torn and people are desperate to leave, but its not the norm. Even during the Irish Potato Famine, less than 10% of the population emigrated over a 7 year period, which is probably the largest mass migration in European history.
Now, Poland is a much more comfortable country than some, but I think that probably only around 5% of the population of the world would seriously consider emigrating. I know an almost endless stream of UK PhD graduates who walked away from academia rather than face a post doctoral placement in a European country, people just don't want the hassle of a new language, a new culture, making new friends, etc. Never mind the fact that your romantic partner might not want you to go.
That means that there might be as many as 400 million persons in the world who would emigrate given the chance, and what fraction would come to the US? Maybe half? So your absolute worst case estimate is maybe 200 million. Now that is too many, the US could not absorb 200 million without serious problems, so maybe you don't do that, maybe you expand a free movement zone a bit at a time. Suppose the US struck a trade deal with Mexico that included free movement between the US and Mexico for Mexican citizens, in return for which mexico would secure its southern border. That is a totally reasonable. That is just the same as the EU did with eastern Europe, and it was not a problem. You could legitimise all your illegal Mexican immigrants, and those who come to the US return to mexico exporting US culture and creating a strong regional ally - nothing breeds peaceful coexistence quite as well as an exchange of culture. The US could, as part of its free trade agreements, steadily widen its free movement zone, maybe signing one with the European Union, and then, some successful southern american countries. This is what most practical and political people mean when they say "opening the boarders".
In time, a free movement zone including the EU, US Mexico, Japan, Australia and South Korea would be a model that other countries would want to join, and, like joining the EU, you could let countries in in return for government reforms that helps the west obtain their strategic goals. You could practically write a minimal constitution for it: Democracy, Free Media, and independent judiciary. It would be the highest form of a free trade partnership, and everyone would want in. It would be the absolute best way to use soft power and cultural exports to bind countries together strategically.
I mean, open boarders has challenges, but its not like anyone is saying just let absolutely everyone in the world come immediately. But I think free movement is the natural extension of free trade, allowing people to share culture, education, and technical skills learned in "the west" and binding countries together. How long before Russia and China wanted to join up? Better cultural exchange would erode barriers and reduce tensions between cultures that are very different and often seem to be talking past each other.
