President Park Geun-hye expressed shock Friday after two handicapped people were rescued last week from a salt farm after years of slavery-like labor, saying she can't believe such an incident happened in the 21st century. The two in their 40s, one of them mentally handicapped and the other visually handicapped, were coaxed with job promises into the salt farm on an island off the southwest coast in 2008 and 2012, respectively, and were forced to work like slaves with little sleep and no pay.
