First of all, Albania and Kosovo are of course not members of the EU. Kosovo is not even a country. Neither does my country officially recognize it and neither do I personally recognize it. Many countries don't recognize it, it's like Tranznistria as far as I'm concerned.
Second, I don't think this wave of muslim migration is a bigger problem than the one it is trying to solve. Europe populaltion will be cut in half by 2050 or 2100 if I remember the stats right. Europe will no longer exist very soon, and that is a huge problem since EU and USA are pretty much the only democratic countries in the world, therefore the only ones with the capacity to become very rich, productive, fair, free, etc. Dictatorships can never achieve high economic development due to the corruption such systems bring. If EU and USA population will get at 25% of what it is now, the economic power, military power, etc. of the good guys in the world will be destroyed.
And third: At least the muslim migrants are caucasian as a race and therefore have a good average IQ. And even this isn't helping too much. Besides groups with lower average IQ having higher natality rates, a probably even bigger problem is dysgenic reproduction. Ever since the modern age, whatever the group, people with higher IQ make much fewer kids than individuals with a lower IQ from the same group. This is creating a downwards pressure on global average IQ, which is highly correlated with PIB per capita and democratic development.
And last but not least: It should be expected that democracy and the high development that such a system brings will die one day, probably before 2300. A democratic system is quite an unusual development. All the pressure in the world is pressing towards dictatorships. As a person living in an eastern european country struggling ever since 1989 to become democratic, I know better than anyone else how difficult it is to implement such a system and how easy it is for it to dissappear in an instance. Look at how putin is assasinating journalist and political oposition but has 80% real support due to control of the media and effective propaganda.
If we look at what happened after 1989, things look pretty bad. Despite USA and EU gaining a hegemony of word power, they didn't really achieved too much in terms of promoting democracy. Barely half of estern europe became at least somehow democratic. In the rest of the world almost nothing changed. And these democratic developments can be reverted in an instance, as it happened in Hungary or Russia.
Giving all these problems listed above, I stopped thinking too much about the future of the world and especially that of Europe since it doesn't look too good. Just stop thinking about it. Think only about what you can do in the short term to prolong the good days that we live right now for as much as possible. There is little we can do about the future. The golden ages of development and freedom that we are living right now was bound to be impermanent too.
