>There is no Western country importing unskilled immigrants.
That was exactly what govs did here in western europe for our mines (to strikebreak) and what they do for harbour workers and few other industries still.
It also incidentally makes up most of the migrants coming in even if they aren't technically imported. Sufficient open doors, incentives and looking the other way to form the expectation of likely settlement ends up amounting to the same though.
>The "yield" from crying babies is not 100%. Some will die before their productive years, some will succumb to disabilities, addictions, delinquency, or simply choose not to study and work.
Importing an immigrant cuts away all that "shrinkage", at zero cost to the receiving country (their country of birth bore that cost). It's such a good deal it's a no brainer, basically like planting a tree that grows money. Not to mention it's immediate. Crying babies have a 18-22 year lag time.
I can only feel utter disgust at that kind of rethoric. The idea that a state works for it's citizens and a nationstate advances it's nation(s) is anathema replaced with treating people like fungibles economic tokens.
It also doesn't hold up since the lifetime contribution of your average non-eu migrant ends up negative in more expansive studies. (With extreme variance between origins.)
What's next? Are we going to have shortsighted economists pushing citizens to emigrate again when they don't fill their desired economic roles (like the UK did during windrush times) and replace from abroad to maximise their average economic output?
