Happiness-wise South Korea ranks 41. ( http://en.wikipedia.org/wiki/World_Happiness_Report ). Here in Switzerland (3rd in happiness) it is not unusual that people are employed only 3-4 days / week and still make enough money to live well. I don't know of any other country where this is commonplace. (Full disclosure: If you're from the EU and looking for a tech-job over here, I'd be happy to help out).
How important is it to speak German?
