How do Germans feel about Turkish immigrants?

I spent a year in Germany last year, and the overall feeling is that there are many Turks, but most of them still live in the middle and lower classes of society, and the number is very large. Some Turkish children will go to some poor schools, and they are a little ignorant ~ ~

And it gives me the impression that I don't like Turks very much. I think many people's eyes are disgusting. I don't know why.

Living in Germany does not feel obvious racial discrimination, but Turks rarely enter the upper class or even the middle class in Germany. Many just open small shops or sell manual labor in some factories.

I asked the Germans why there were so many Turks in Germany. They said that Germany lacked labor after World War II, so they relaxed their policies, and labor from many countries, including Turkey, flocked to Germany.

The German teacher over there also told me that there are even some Turkish living areas, that is, the circle is full of Turks, and many housewives in their 30 s and 40 s come to Germany with their husbands, but they still can't speak German after living in the Turkish circle for 20 years ~ ~

Personally, I don't think Germans exclude Turks, but they are not treated fairly. In addition, Turks have caused many social problems in Germany, and many of them live in the middle and lower classes, so Germans have some discrimination against them to some extent.

This is my personal experience living there, for reference only.
