It's because it is. The money they get from intubating and all care required covers the cost and makes a little profit, but there is no reason at all why they would do that to a person that doesn't need it. It takes a heavy toll on the doctors and nurses too. If a hospital director would run rampant and tell docs to willy nilly intubate someone it would be all over the news and doctors wouldn't agree to it either (they are in very short supply in Germany and wouldn't bother putting their reputation on the line).

You also have to be aware that around 25% of all Germans are in one way or another prone to believe in conspiracy theories, e.g. great reset and so on. Sadly I only have a German source on this, but this was a major point of discussion in the long running "Mitte Studie" which is one of the best and most rigorous studies about Germans and their political beliefs.

source for what? you're welcome to use google btw. might save us some time.
