In Germany you can get by with pretty much any job. If you don’t earn enough you can apply for welfare. It’s a pain in the ass, but better than working yourself to death. If you want more, you need a good education. Generally speaking, the better your education, the more likely it is that you can get by with only speaking English. But wages are lower than in counties like the US.
