- checking on the numbers, the minimum wage in South Korea for 2011 was about $3.75. I'm guessing when I first went there in 2003, it was even lower.
- in 2006 I visited and remember having to make my way around a gauntlet of guys in doorman uniforms, who's job it was to bow to people entering the hotel, and another guy who's job it was to push the "up" button to request an elevator. That's it, that was his entire job. For eight hours a day, he stood outside of the elevators, waiting for guests, and pushed the only button to request an elevator (there was no down button the hotel I was staying in).
So yes, while the unemployment figures were pretty good, the actual "work" that people were doing was essentially meaningless.
I've never been to Japan, but I'd be highly surprised if there weren't similar analogues.
