Earlier quoted context omitted.
I was speaking to Europe in general, but good to know about Germany specifically. I was asking about Europe generally because it seems like I’ve heard of a number of European countries struggling with declining populations in recent years, and if it’s a problem throughout the EU, then perhaps the EU would be better off by loosening its immigration requirements.
It's mostly a problem in countries that aren't doing well economically and thus their young people leave to other (mostly also European) countries. You cant make immigration easy only in these countries as once you are in the EU you can then move to any other EU state (there is some wait required, like a year I think). So people will basically use these as a jump off point to the countries they actually want to go to…
But yes, investment in poorer countries also seems reasonable.
