One of the strangest phenomena in Korea lies in the contradiction that while there abundant human resources, there are no available qualified workers. This is because there is an extreme mismatch between demand and supply in the quantity and the quality of the human resources. Although there are more than a million unemployed adolescents wandering on the streets, industry could'nt hire skilled workers even under the IMF economic crisis, thereby having to import more than 350,000 foreign workers, some legal and some not, under the name of "industrial skill training program of foreign workers". Although Korea has world's highest college entrance rate, producing more than 250,000 graduates per year from four-year colleges, highly qualified workers in the research and development areas are still scarce and practical engineers in the manufacturing factories are very hard to recruit.
