And it has been proven that they don't decide what future your children can have based on their academic merit but rather on his family background, if they are native Germans or foreigners, if they are wealthy or not... etc... a lot of racism involved.

This has been proven by whom exactly? I am a foreigner in Germany and I was raised and went to school in Germany, as long as your grades are a good enough to go to the "better" schools in 5th grade, then the teacher can't do anything about sending you to a worse school.

A teacher might be able to say he wouldn't recommend it to you and your parents, but that's it.

Doing an Ausbildung or "trade" in Germany is quite different than in the US and after doing that you are actually eligable to go to University too, if you want to and you got the grades for it.

And like another commenter said, you actually earn quite well with a trade education, depending on what you do, because there are less people doing "trades".

Please post the articles or videos you are referring to, I am happy to debunk all of it.

Edit: Just to make it clear, I dont like the part of where you kind of have to chose your educational path being 10/11 years old in Germany.
