There are good reasons to go to Germany, like relatively high salaries (it always depends on where you're comparing. At least in the fields I'm about to work in you earn significantly more in Germany than in Austria), high security, good schools and universities, ... (similar to Austria in that regard, maybe slightly worse).

The only reason against Europe in general is that you pay a lot for mandatory purchases (a home (doesn't matter if rented or bought), groceries, ...). Personally I still prefer that over cheaper costs of living but less security, worse child- and healthcare etc. but something has to change, because it's only getting more extreme.

If the development of 50 years ago to today will continue for the next 50 years something like a civil war is inevitable.
