@saxnot The devil is in the details, since I cant read german I may not understand the system well enough to ever be able to give my opinion on it.
I can say that having a job center to hook you up with jobs sounds like a great approach as a last-resort and should be conditional for anyone getting assistance.
In my mind people without work make up one of two groups 1) people who are too lazy or unmotivated and simply do not invest in themselves enough to acquire marketable skills that they can then get. 2) People who are more than willing to work but don't have the money to acquire marketable skills and their current skill level not sufficient enough to be hired.
Because of the existence of #1 any system that helps financially through free education and job training programs needs to make a condition that they will only provide that help so long as the person is doing their part and putting the effort in at all. Therefore people should be given the option to either pursue a free/accessible education/training program or prove they are actively looking for and willing to accept work. Part of that is a job placement program that is required participation for anyone on welfare who cant find work on their own and is not participating in education/training programs.
