That's funny because in German medical degrees are a lot more prestigious than titles from other scientific fields and a doctor (Dr.) is usually harder to get in this field than in others because of all the stress and risk involved with this job.
This is patently false (not the prestige part, but the rest). To get a doctor's degree as a physician in Germany is absurdly easy. You pick a topic and write a few pages about it. Or let someone else write it. I personally sat in "final" exams where the candidates didn't know what "they" wrote in their thesis. They did not fail, but were told to read it first and come back again in a couple of weeks. Then you get your "cum laude" or "rete" and can call yourself "Dr. med."
You can also make a real degree that needs years of work, a longer thesis, and ends with a completely different and difficult final exam. This one will yield a better grade and the option of a university hospital career, but the difference is invisible to the public. If you just want to have a nice certificate to hang on the wall in your waiting room, you don't really need to put in much effort.
I highly doubt your "observations" and you are aware that you have to successfully study already over 6 years to get it with actually working in a hospital on patients? And what exactly are you talking about with "a real degree"? You mean a Dissertation? Btw. a Dr. title is an additional qualifikation in Germany roughly comparable to an international Master degree (which we get forced to use in Germany, too).
The only thing I see is that you have absolutely no clue about this. As I said, I have been sitting in "Dr. med." exams. Whether you work with patients or not is irrelevant to your Dr. med. Of course, you need to work with patients to pass your state examination as physician. For your Dr. med., you can also measure the fat content in fries done at different temperatures, if you are so inclined. Or just do some weeks of literature research. Most "Dr. med." titles have no worth whatsoever.
I already explained what I meant with "real degree". You work several years on a scientific project, write a thesis and have a more difficult exam. The institution where I experienced this reserved the grades "summa cum laude" and "magna cum laude" for these cases. The exam was then in front of a committee of about 6 people, with talk and subsequent exam by the committee. The throwaway titles (which meant the candidate declared up-front that he would not try to achieve more than "cum laude") had an "exam" that consisted of a few minutes of a nice conversation with one professor and one guy as witness and writing the protocol. Failing was not an option (as I said, the more egregious cases had to return later). The degree practically excluded the candidate from a university career (universities know what that grade means), but the wall certificate comes without a degree written on it, so who cares. Everyone in the room knew that this was only done because patients expect their physician to have the "Dr." in front of the name and that the whole procedure was otherwise a meaningless charade.
Physicians outside of university hospitals don't need a doctor title. They are the equivalent of a highly trained technician, not a scientist. The problem is that the public thinks that, without the two letters "Dr" in front of your name, you are not a real physician, although that is actually decided by the state exams. Not doing the doctor title is a financially bad decision, as this will have repercussions from unfulfilled patient expectations. And that's why this charade is done.
