Yeah, I have noticed exactly the same thing in Germany. There are some nationalities doing low-paying jobs in disproportionate amounts. Turkish for example, the largest immigrant group here. If I divide my current company by "high paid" and "low paid" jobs, Turkish (plus Germans with Turkish background) are over-represented in the "low paid" half (more than 60% I estimate). On the other hand, there are only a handful in the "high paid" part (no engineers, for example, only a handful engineering-adjacent). These exceptions are often people coming straight from Turkey, from wealthier backgrounds, rather than 2nd/3rd generation German-born. This has been the situation in pretty much every company I worked or observed. With recent housing problems, they also don't have as many options of where to live, so they end up in the same neighborhoods, where they rarely have a chance to speak German, let alone to integrate with the culture. Integration courses are crowded and extremely difficult to get into. If you're working full-time it's borderline impossible to find something after 5-6 PM. Religiousness also plays a role in making integration via integration courses hard (EDIT: but Turkish are more secular, this applies more to Arabs), there are specific classes for women, which is often composed only of Muslim women (since there are so few women-only classes, Muslim women are given priority), so few chances to chat with non-Muslim women. One interesting anecdote that I can't prove, but I see a lot of people moving to Turkey in large numbers. Some of them are 2nd or 3rd generation and have never been there. Life is not easy.
