All I have today is a link to a New York Times opinion piece about the adoption system in South Korea. It's written by a woman who was born in Korea but adopted by a family in the United States.
I'd recommend going on to read the comments sections, as it has some interesting thoughts about not only adoption in general but South Korea's attitude towards orphans, single mothers, etc. I'm not sure I agree with some of the things that are said on that issue, as Korea is rapidly changing and there is a huge difference in the attitudes of younger and older people. Nevertheless, international adoption is a very important issue in Korea, and this article raises some good points for discussion.
