I assume there's the same problem as in the U.S., of getting young people to show up at the polls, much less getting 'em engaged in issues of property tax, zoning, etc. On the other hand, in the U.S. old people are hardly a solid conservative voting bloc, esp. given their having been socialized during the height of the union movements, and being themselves the beneficiaries of the basic Democratic Party social welfare reforms of the 20th century (social security, medicare, unemployment insurance, labor laws, consumer protection). Not sure how anything like this plays out in Korea, which didn't have its first free elections until 1988, and earlier had its left harassed and crushed by three consecutive dictatorships. Not that I know much more than that about Korean history.
