Aging population. Countries with aging populations need to import young people from other countries.
Encouraging people in Western countries to have more babies a) won't work, we don't want to b) takes 20 years and c) seems silly when the earth is overpopulated. Redistribution makes more sense, and you're not going to get young people from Scandinavia or wherever would be more acceptable to you, because they also have aging populations
If you don't want immigration, you need to find another solution to the looming ageing crisis. Clones?
I do agree with this. Importing people is a viable short term solution for countries with really poor birthrates. I'm looking at Germany, South Korea, Japan etc. There's just something about the more educated + more liberal = less birth that seems easy to solve with the less educated + less liberal = more babymaking. However, countries do need to consider their own identity, and the long term ramifications of unchecked immigration... that is, if they really truly care about their genetic and cultural identity.
That being said, I have an even more controversial perspective on this, which is that the Earth belongs to us all, and yes, borders matter for economic, political, and military reasons, but for almost all of history, humans were free to walk and travel the world, to leave their place of birth and settle down somewhere else and start a new settlement etc. Then eventually there came a point where most of the known world was already "settled" or "claimed" and it became harder to just waltz somewhere and do your own thing (you could do it as an individual up until maybe a few centuries ago, but it was impossible to start your own "nation" so to speak, for a while now) however, before the UN, wars of conquest were a thing, and if you had enough people in your army, and you really wanted to be in some particular place, you could try your hand at taking it by force. IMHO, this was reasonably fair, and allowed people to move freely and settle freely provided they had enough people to do so. It became a little less fair with modern technological progress creating vast discrepancies between various nations, but still, the world had a way of balancing it all out.
It pisses me off to no end, that now that the "world powers" are comfortable in their little seats, they decided to ban conquest, and post-911 the constriction of the ability to freely travel. And for that reason, I think some countries/cultures have resorted to "conquest by immigration" which I think is actually fair, given that that's the only option people have now.
I absolutely don't believe in the concept of sovereignty as a right. I believe that sovereignty must be fought for and defended, and decaying/collapsing empires deserve to be invaded/occupied and succeeded by superior military, cultural, or political forces. That has been the way of human evolution throughout history, and is a critical catalyst in the betterment of cultures/societies via survival of the fittest. The lack of which has caused undeniable stagnation and corruption of western civilisations.
Yes, it makes me personally sad to see the demise and steady erasure of western culture, history and architecture, but it is the way of the universe. What cannot be defended does not deserve to exist. Fuck it.
