I don't understand the word "we" in your comment. Obviously, some specific people do the actual work of caring for disabled people. Most people don't do that work.

The point of "Zivildienst" which translates to "civil service" as opposed to "Wehrdienst" "military service" was to make conscientious objectors contribute to society in-lieu of serving with a weapon. So, once you came of age you had to do one or the other.

I think within this previous paradigm of a citizen army, as opposed to the volunteer army of professional soldiers we have now, this was a good way to make sure you'd still have recruits while not forcing anyone into the military that really didn't want to be there.
