Fair enough. You should assume when I comment on politics, I am generally referring to western socialist democracies with capitalist economic markets.
I would think non-market economies are relatively immigration proof as the whole reason most people are migrating is that they come from authoritarian or socialist countries with dirt poor economies. It makes little sense to undergo the upheaval and culture shift required for migration just to get to another authoritarian or socialist countries with a dirt poor economy.
I know, I know, "dirt poor" is a subjective term.
But the crux of my argument remains the same. Legal migration only, if a country wants to set that legal quota to zero for a period of time, that's fine. They key is to get the structure defined before it's too late.
It seems that now we have hit the wall where you can't really follow me.
Since you don't understand the details of living in the Slavic world. However I will dive exactly into that (since I feel like it).
For people like you this topic comes down to "Communism is bad, but we won". However to most of you no one really tried to get into details of what happened after the fall of Berlin wall on the eastern side of the wall. Therefore now you have cultural shock over the war in Ukraine. While if you watch my posts here from a decade ago I was saying that there will come the time when Russia will blow up the world order. I mean that is ok, not even western politicians believed us that war of this scale was possible in Europe. However that is simply negation of how Eastern Europe works.
Therefore I know about what you were talking about, however if you are talking about that you aren't talking about my part of Europe . Which is still in the transition between Communism and Capitalism, since it is to the east of ex Iron Curtain. Although when it comes to my living environment the transition is kinda complete for the most part. My local economy in it's current structure is fairly similar to the ones in Western Europe (which is still visibly to the left of North America). Plus the growth is about 3-4% growth and public debt is falling for years. Therefore in a sense it is actually doing much better than typical western country at this point. Cynics would even say that it is doing much better. However some of that is evidently due to the fact that many key/basic segments of economy aren't privately owned. What allows the government to keep the prices unnaturally low and thus it avoids the worst of inflation and similar problems (which we kinda can't really afford). After all in the region where dictators and war are never that far away it is actually smart to keep the basics as public property. Since you have to prepare for the scanario that business as usual could abruptly stop at some point. This is exactly why here COVID caused minimal cultural shock at the start.
However all that doesn't mean that there isn't substantial number of those that want to fully turn back the clock, so that things are more like before the fall of Berlin wall. What is the demographic that doesn't really exists in the typical western country, since all these people ever experienced are various versions of Capitalism. Although it is worth mentioning that most of that demographic that wants to turn the clock around are older people. Since these are the people who never really adapted to the economy that is more market based (since old people aren't overly adaptive in general). Plus in the transition from one system to another many of them lost plenty in the terms of jobs, saving, retirement etc. Therefore they think of the new system as some sort of scam. Especially since in schools they were thought that capitalism is a scam. What kinda came to life due to region wide pretty messy transition from one system to another. However with generational changes that is the glitch that will sort itself out for the most part
However what is quite likely to stay is the political right, which dreams of nation states across the region. After all these people didn't really crash the Communism so that we become the countries that import large number of random people from global south. While the difference that these people are legal or illegal immigrants is kinda irrelevant for out local conversation on the topic. What is because that was never the plan behind why the Berlin wall came down. It came down so that the nations behind the wall can build their own nation states on local culture and history. Not some experimental left wing ideology that is full of contradictions. That is why the wall came down, not because we really wanted to be exactly like you (here is making collective not personal statement). This is exactly why all post Communist countries have rejected large scale accepting of various refugees. While even the experiment with legal and economy based immigration isn't really to the liking of most (in the eareas where it was actually tried, since in some it wasn't tried). Therefore most countries in the region are trying to develop alternatives to mass immigration of foreigners (as explained before).
But the story doesn't really stop there. What is because many people in establishment(s) realized that on it's own this wouldn't give too much in desired results if the Western Europe becomes too multicultural. Since being in the sandwich between Russia and multiculturalzied western Europe probably wouldn't make for that great future. What started the project of pulling the Western Europe back into more traditional mindset. The project that seem to be going above expectations if we judge by the current headlines. Since the multiple crisis have hit and now the consensus in Western Europe is trying to find some sort of new normal. What can be directly seen in how centrist and liberal progressive forces are losing steam all across the region.
Here I will stop with the story mode since all of this is getting too long. However that is story of why this part of the world will never really accept some of the worldviews that you hold. It isn't personal, this is simply what you in North America are calling "local culture". It is what it is.
