As I have said before, Doh. I only accept the principle of migration where this promises a benefit to both parties.
That principle was of course the premise upon which the League of Nations was prepared to endorse a degree of ‘Jewish Return’ to Palestine.
And so? Yes. As nation’s gross GDPs rise but their per capita GDPs dwindle to the point of real declines (through increased pressures on service infrastructure, housing provision, the domestic law and order circumstance); the opportunities for migration can be expected to decline.
