That's only half true. You have lots of trained and experienced people willing to do this job despite the low pay because some of these people wouldn't function in a field where they couldn't help other people, even if they sacrifice their own health and financial situation for it.

The issue lies with state subsidies for employing refugees which currently mainly targets Ukrainian workers, though they'll never outright say it: https://www.arbeitsagentur.de/unternehmen/arbeitskraefte/gef...

If you have a job to offer you can now decide if you pay a German out of your own pocket or if you hire a Ukrainian who will end up being cheaper for you because the state supports you in doing so.

Have seen this with bicycle mechanics, nurses, nursery homes, lots and lots of cafés.

Goes without saying that I like Ukrainian people just as much as I like Germans, Syrians, Iranians, Russians, etc.
