The actual analogy would be a world where you need to get a visa per-magazine to read the articles they have, to the which you might not qualify.
A newspaper-immigration-patrol would look at this comment of yours on HN and possible deny you access, you should watch out.
> What are these institutions, and would they be damaged at all by free movement? If the people in good_country made the institutions, and they get demographically boxed out by people in other_countries, what happens? What are "institutions," exactly? Why did other_countries grow bad institutions? Would emigrants damage those countries further? The article semi asks these questions then drops the thread.
A great open question is what happens to institutions when there are culture changes. But bear in mind that without immigration, there would be no institutions in the U.S. whatsoever. It is a point of view of past immigration being great, but current and future immigration being bad, which I think it makes very little sense holistically speaking.

There really isnt a limit on living space. The rent is high in places like the bay area precisely because moving there is still a good deal. Problems of residential prices are widely overstated.
