To the part about parents selling their children into slavery. When I was in Korea, there was a village not far from the base called A-Town. It was full of bars and clubs and such. A good portion of the bars had female bar flies in it, and they were a part of the bar staff. They would approach you, try to get you to buy them an expensive juice. As a result we called them "juiceie girls". These girls would very many times take payment for sex. Well whatever money they earned went to the bar, and that money was to pay off a family debt of some sort.

A-Town has been there since our occupation of Korea.
