One major difference is labor laws. The EU has far more protection, but far less mobility. I remember telling a German friend that I had gotten a new job operating a fairly large power system, after working in a tangentially related field, without any additional study or licenses, and his response was “Only in America!” I hadn’t even considered that this move would be far more difficult in other countries.
Also very German to rely a lot of degrees and certifications. Other countries like the UK (European still even after Brexit) would care more about experience than degrees.
