Korea has a number of other jobs, but some are low-paid service work, and many others — in factories, farming, fishing — are scorned as 3-D jobs (difficult, dirty, and dangerous). Educated Koreans don’t want them. So the country is importing labor in droves — from China, Vietnam, Cambodia, the Philippines, even Uzbekistan. In the countryside, rural Korean men are having such a difficult time finding prospective wives to share their agricultural lifestyle that fully 40% of rural marriages are to poor women from those other Asian countries, who are brought in by match-makers and marriage brokers.
