The study by the German Centre for Integration and Migration Research (DeZIM) found that 21% of respondents reported thinking about emigration. Among Germans without a migration background, the share was 17%. Those who themselves immigrated to Germany were twice as likely to consider leaving (34%).
Doesnt mean they think life there is bad. Theres nothing wrong with having curiosity about how life is around the world and wanting to try it.
I imagine it‘s mostly the usual complains about kebab prices and right wing topics. They‘re not actually serious about leaving. It‘s your usual all talk no bite.
Another thing are some people who migrated perhaps. Germany has become a much less welcoming, open and progressive country as of late. Some of them could leave and contribute to society somewhere else if the radical right keeps being normalized here.
