As a fellow german, but not a Fachinformatiker, I suspect colleagues without a degree still have a hard time to work their way up into more advanced management roles or just into the higher income brackets. I wish that would not be the case though. What I find intriguing, although I'm surrounded by "Programmers", almost no CS! We have physicist, mechanical engineers, mathematicians, historians and english majors even.
