- At times too organized: You get a ticket for biking on the wrong side of the biking lane; Some people give you wild stares if you walk across a red light or if you do the recycling wrong (a.k.a not removing plastic caps from bottles before you throw them into the glass container)
- If you don’t speak German, it might not be easy to break into social circles: Although young people generally speak decent to perfect English, it seems to be quite hard for foreigners without proper German to really bond with locals (exception is Berlin).
- Customer Service people are way less friendly than in the U.S.: Biggest culture shock for me in the U.S. was how friendly all the people in super markets/on call center lines were.
- People are not as entrepreneurial/adventurous as in other parts of the planet: In the U.S./China everyone seemed to have their side-hustle or were running this or that organization. I would say there is less of this kind of spirit in Germany.
- Public/Bank Holidays: Not sure if there is any country with more official bank holidays, but Germany (Bavaria) in 2017 has 14 compared to 8 in the UK; with the average 30 days vacation you get from your employer, you can easily take six/seven complete weeks off work
- Quality college/university education (and all other education) for free: Might be relevant if you come to Germany to study or if your kids grow up in Germany
- Well functioning legal/administrative and constitutional system: Yes, people complain about bureaucracy, but only because they haven’t seen how it works in other places. Courts are on average much more efficient in Germany (average case closes in around one year compared to six in Italy) and the Constitutional Court strikes down even prestigious legislative projects.
- Rent and stuff is cheap: Compared to London, Brussels etc, living cost in Germany is super cheap; honestly I don’t know how they produce the stuff for discounters
- Quality of houses, buildings in general: Windows in particular have awesome insulation against everything
- Other stuff that has already been mentioned by other people, like safety (crime rate), health insurance, public transport
Edit: Of course someone had to point out that the real cons of living in Germany are “Terrorism, rape, Merkel”. For the first two, anyone is free to check out official statistics. Both the intentional homicide rate and the rape rate are doing pretty ok in Germany. As for Merkel, I might not agree with everything she does, but I prefer her way more to Donald Drumpf.
