LP, how can you compare Germany to Qatar?
Here our children (or most expat children) go to private schools, and in that kind of system you get what you pay for, as simple as that.
And I have the experience with different schools to confirm that statement.
I am very lucky to have my child in a fantastic school where all the teachers we encountered are like Adey and his colleagues, dedicated, knowledgeable,enthusiastic.

Show me a public / government school in Germany where that is the case.
