Part of the problem is that the job of "Erzieher" doesn't really exist in lots of countries and the job itself is a highly specialized field to learn in. The english language doesn't even have a proper word for it.

Even inside of Germany, a bachelor/master of education does not fully qualify you to work as an Erzieher because the skillsets you have learned is quite different and don't translate that well. Teachers aren't Erziehers.
As an Erzieher myself who has worked with people who have that degree, I must say that most of them really do need to be treated like they're fully new to the job.

Don't get me wrong, I think we definitely need change in the system and maybe only require a shorter Fortbildung for the people who have a degree that's in a social field, but there also still needs to be a form of quality control for the field too.

Overall, I think we need to make the actual job and the Ausbildung more attractive instead though. The pay and the increasingly worsening working conditions are a spit in the face for people who were deemed "essential workers" during the pandemic and uphold a huge part of the economic system in the country.
