This BS, nonsensical phrase was mentioned several times in the article.
I live in Spain. Their population has been rising the past couple of years due to migration, not births. It's also one of the reasons Angela Merkel wanted so many refugees to come into Europe, to replace aging workers. The problem is that as these workers come in they bring their culture along with them and soon the country becomes unrecognizable. They think that one of the reasons Europe is so clueless about this simple fact is because so many of their leaders have never had children themselves.
America isn't that far behind Europe. I was still living there when salsa replaced ketchup as America's most requested condiment and you had to press a certain key on your phone to get an English speaker. The West is being destroyed from within.
It should be the primary reason to LESS immigration to the country in order to keep the culture
If the predictions are accurate, then there won't be anyone to migrate in.
