Of recent date I have tried to refrain from posting, but this OP and discussion are so intellectually blind and dishonest I can't refrain here.
"Morality" has nothing to do with this discussion. The days of "[STRIKE]white man's burden[/STRIKE]" "America's burden" to save all humanity in my estimation fell by the wayside long ago. Morality as an unquantifiable burden of guilt projection is not salvaged by sleight-of hand adjectives, adverbs, catch phrases or -isms.
The only relevant matters to discuss are:
(Projected available resources) divided by (projected population) times (resource allocation per inhabitant).
Instead of talking categories of workers we should be discussing mouths. And ballot consequences should not be germane.
The immigration debate is a way to avoid the above factors; it is also stands in default of an honest discussion of the social engineering required. Increasing or decreasing immigration will most likely not have any of the palliative or deleterious effects cited. Instead of relying on immigration to have one's desired effect we should institute policies that demonstrably give the outcome society determines.
I am neither a
Malthusian nor
Cornucopian, But on the whole I think Malthus was more right empirically than the Cornucopians. (Malthus was wrong in timing, not in theory.) I will not recite the perils the world's food supply enjoys. We have all - or at least the sentient - heard or talked about "peak oil;" a more pressing problem - with immigration or population shifts - is "
peak water."
My equation above is not holy writ, but it is Chapter One of the discussion that was disguised by the one posited.
If our future supports immigration, fine; if we feel it does not, that's fine too.
