Never heard of that in any of a variety of news sources I consume, without a credible source I heavily doubt it. Instead it seems like doctors currently urge people to take precaution (like getting vaccinated) to keep them away from hospital because of the work load.
> Recently went to the doc for a normal cold. Was standing in a small unventilated corridor for half an hour with several coughing people.
A lot of doctors now offer visits via video chat, if you need a sick leave for work it's often enough just to call the doctor and they send you the papers.
True, there are problems with resistant bugs in hospitals and there are problems with testing facilities. The 'ashamed, stupefied and angry' feeling in Germany however can't be generalized like that: Some feel like they're living in a dictatorship because they have to wear a mask, some are angry because of the unclear and reactionary handling of the pandemic on a political level, some don't believe in science but follow alternative medicine or just think all of it is a big hoax, and there probably many more reasons people have.
Overall, Germany still has a pretty good record on keeping people alive while never using really hard measures. What we really could use though is a more civil communication.
