The suggestion that these countries are doomed due to population decline is complete nonsense, as Japan has shown. Automation is enabling less people to have to work to maintain the same standard of living. As you said worst case scenario immigrants could fill in the gap (certainly no shortage of people trying to immigrate to western Europe). Social cohesion could go down, but that doesn't mean the only option is American style "every man for themselves" hypercapitalism.
