I did notice that there are well-paid jobs advertised there, and I have taught Korean people in the UK.
I'm just wondering what it would be like to live there though. One of my friends in Japan who had experience of both countries said that "Korea has all the bad things about Japan without any of the good things"!
I suppose the only way to really find out is to actually go there. I have only been there very briefly, when my plane was delayed, I stayed over in Seoul.
