Encouraging open borders and mass immigration is not the only permitted immigration policy.

Most countries in the world, including large and economically developed ones like Japan and China, do not have this policy. In fact, even developed countries in the West do not have such policy codified into law - quite the contrary.

It is highly disingenous to suggest that it is the only option and to preemptively scold the reader for thinking any other options may be considered. Even worse when it is done in such form and in an article suggested to be a pop science piece instead of a political pamphlet.

The quoted statement will never ever pass a NPOV check.
