It depends on the kind of people you want. Even if the town is "remote" if seen by German proportions, it is still only an hours drive away from the next major cities and the countryside is very rural and beautiful. It's true that these are not the conditions that attract a lot of people straight out of college, but they are very attractive to more senior people, esp if they have family. I know Grohmann has been very good at binding talent for long times, i.e. by giving loans for houses at much better conditions than a bank would. So these people build their homes in the area, which ofc gives them a much greater tie to the place.
