What's the point for the native citizen of Netherlands or France in moving to Germany? The quality of life and salaries are similar, but the culture context is just so different between these countries. Completely different languages, different customs, etc. The numbers surely confirm that - the France is in the bottom of the list, and Netherlands are not even included. [1]
Anyway, out of ~14 million foreigners in Germany only 5 million are from other EU states, and most of them (~3 million) are from Eastern European countries (Poland, Romania, Bulgaria, Croatia and Hungary).
> In Sweden at least, immigration was always biggest from neighboring countries (e.g. Finland/Norway)
There are less cultural differences between Sweden, Finland and Norway. At least they have more or less similar languages (ok, Finnish is different, but Sweden is also an official language in Finland).
