Back on topic.
One of the core issues about the whole EU debate is about people not being able to get their heads out of their asses. The world is bigger than Germany vs Britain or France. Bigger than the Netherlands, bigger than Greece hating on Turkey or Serbia hating on Albania, and vice versa. In a larger sense, the European nations and the US have everything to win by standing fast together.
It will only be easier to deal with China and Russia that way, or even just the EU/US power balance. For example, Britain is far more likely to get a good deal with the US, standing within EU, rather than bilateral deals. Britain simply needs the US more than the US needs Britain.
Europe has more in common within itself, than with the rest of the world. That's why it should be in a union of some kind. Thats why it should be easy to travel and work inside its own borders. Just look at donkey team. It would be impossible without the EU to gather a team across 8+ nations. This ability to fluidly move across borders is a large part of what makes the US such a powerhouse, and Europe is also becoming more like this. Like it or not, I think it is for the better. I see it in my own life, I'm considering where I want to live and what I want to do.
(Strongly siding on Poland(!), since quality of life, safety, and bang for buck is very high, if you can generate income based on export of your talent/work.) This mechanism is freedom of travel + capitalism in practice.
Now about the refugee situation, I think it is a slowly self-correcting mechanism in place here. It's just a huge sluggish machinery that sometimes takes years to react and end up with a reasonable mechanism to deal with it. As right wing parties pop up everywhere in Europe, the politicians will take note, and eventually adjust their policies.
Europe and the EU _will_ eventually become way more strict about immigration. Way before its "too late" as some people think. How it will go down? The traditional, moderate parties will wake up to record polls for the right wing populists, and begin to change their policies accordingly. Sometimes the populists will rule in coalitions, and also be forced to moderate themselves by the realities of politics, eventually becoming as indistinguishable as the rest of them.
This is the utterly boring truth.
It would also make sense to deal with the root causes of immigration, which apart from direct causes like war, is a deeply stratified world. For the first time available for anyone to observe and interact with through the internet. Now anyone can fully observe what shitholes they live in. (The majority of the worlds population!) For most people, the world is a corrupt, poor, dirty and dangerous place, and Europe is the best place to be. They come, because they can come, and good luck keeping them out. Reducing immigration substantially would entail blocking off the Mediterranean and the black sea with naval powers, negotiating expensive return deals with Turkey and Russia and all the southern Mediterranean countries, as well as very strict security in all harbours and airports. Internal borders in Europe will only fuck over ourselves and Greece/Italy/Balkans.
Perhaps this is what will eventually happen, but pls understand it takes a while for this kind of thinking to reach the top of the EU. It's not the end of the world yet though. Europe consist of about 741 Million people. Even 1 million a year will not substantially dent the demographics in the short term.
TLTR: Calm down, and think in a bigger perspective.
