I've found this is something that really surprises Europeans. But, once, when I was comparing notes with some travelers in a hostel in New Zealand, we asked a South Korean among us for his perspective. He said that he and everyone he knows gets maybe
2 days paid vacation a year. They work most weekends and get maybe 1 holiday. He said if you want to travel, you have to quit your job to do it, with no guarantee you will get another when you get back.
This changed my perspective. The difference between that and the States' 10ish days off is much greater than the difference between us and Europe. It is hard for me to imagine. Can anyone else with knowledge of East Asia chime in? Was this guy's experience representative? If so, it is a bit silly to call America the "no vacation nation." We do get vacation.
