It’s true that they probably will not start their own butcher’s shop. Then again, what do Germans need? Most want affordable meat, which requires cheap labor. They want affordable houses, which requires cheap construction workers. They want affordable logistics and shipping, which requires cheap personnel.

These jobs are never going to get a top loan because that would cause inflation for everyone. And most Germans aren’t even motivated to work there even if the wages were good, because the work is hard/irregular/dirty.

Western European countries have always needed foreign workers, many of which have become part of our society such as the people from Turkey that came here decades ago. If Germany wants to continue without their foreign workers they would be immediately having around 8 million vacancies even by removing the people who don’t have a citizenship yet. Germany has one of the most aging populations in the world, there’s not a chance those vacancies will be filled without foreign workers.

In Germany, there are truly many vacancies in some areas. For instance, there are around 35k open vacancies for nurses and this number is expected to grow to around 150k in the coming years as the baby boom generation is getting older. Most Germans just don’t like the prospect of working irregular hours and wiping elderly patients’ butts, even though wages and secondary conditions are improving for nurses.
