> Another big problem is the mentality. "We have always done it this way" and "I don't want to change it" is extremely prevalent. I say this as a German.

Interestingly it's not only the domain of the conservatives (e.g. CDU/CSU) to cut any discussion this way. Social democrats (and their voters) use the same argument, just in instances where it fits their program (e.g. labour laws).

The only party suggesting any such policies consistently fails to clear the 5% threshold as of late. Evidently, the electorate is satisfied with the status quo.
