Too many factual mistakes on which your house of cards is built make it difficult to argue on merits. Examples range from "permanent unemployed underclass in Germany" (Germany is close to full employment with exceptionally easy ways to get training and a part time job) to "homogenous cultures in Nordics" (have you ever actually looked at demographics in Sweden?)
I'll just finish off with the simple statement that when someone says "just you see, in twenty or so years it will be different because I say so", that usually means "I have no evidence to show why the outcome I suggest is the realistic outcome, so I put it far enough into the future that any outcome can be judged as possible".
Examples of these arguments were claims that world will end in nuclear conflagration in 20 years back in the 60s, that Russia would be fully integrated into West in 1990s and other similar brain farts. In real world on the other hand...
