They're coming for the jobs immigrants would be taking if the Japanese government weren't so xenophobic.

This is explicitly part of the discourse, but I think it means robotics companies continuing to receive government grants while not actually delivering any labor saving technology, and immigration policy being held back. The industries needing labor will not get a suitable solution, the economy will continue to suffer, but the psychology of those around the world who believe in racial order, and correct positions of alleles on geography, will remain soothed.

> Japanese government weren't so xenophobic

Japanese people are, this is normal.

They look at what happens to people that aren't xenophobic and they don't want that.

Not all cultures are trigger happy with irreversible population replacement dynamics, and simply don't consider mass immigration as a viable option. This is completely normal too.

Unfortunately peoples lives are very short to see things play out in the long term, and in the long term cultures that are okay with population replacement dynamics are very likely anomalies.

What is the point of letting in immigrants if they won't have jobs.

Why does Japan need immigrants? Japan is one of the safest countries in the world because of its immigration policies.
