I'm in a Berlin medtech company closely related to GPs and have multiple other connections to area hospitals. From this perspective I would say everything you've said is entirely accurate for at least this part of Germany, if not the whole country.

It's really a shockingly well kept secret, especially to the outside world. Much like the utterly dysfunctional rail system.

Before the pandemic, I would have said that the country's healthcare system was about a decade away from resource-crisis. Now, it may have already started. I'm terrified of ending up in a hospital, even if there's no covid-wave ongoing. I do not want my life in the hands of the overworked traumatized remnants.

The way this country treats healthcare workers is shameful.
