My neighbor, Jerry Occam, has a simpler explanation:
Stable, or worse, falling population levels are unacceptable to the powerful business interests that are the financial controllers of the political class. They demand population growth any way the politicians can deliver it and the politicians comply.
The loss of the great European culture is an unfortunate byproduct of the resulting immigration policies but it’s the ptice you have to pay if you are going to grow your business.
“Whole volumes could be written (and have been) on the reason for this historic development; and I have no intention of adding to the literature here. What is important is that it has happened.”
I have not yet heard what I consider a reasonable explanation as to WHY this is happening. Yes businesses need workers and customers, but replacing productive workers and earners with unemployable, inbred savages from 3rd world hellholes is obviously going to make things worse. These people cannot be integrated, they are non compliant with laws, have no work ethic and are hostile to the culture in general. It would have been easier to convince European’s to reproduce, or to import workers from China or india, who are smarter, more compliant, civilized and much less hostile than middle easterners and africans.
