The old generation in Korea was born before bthe 1960's when the Korea was very poor economically. They had little chance to get the high education, and grew  up in under-democratized society. At the  a result, they tend to follow the rules (pl) of the government, employers, or other leaders, and have high loyalty to their country or employers. They contributed committed themselves to their jobs, and it played an important role  in to the economic growth.

Aswhile Meanwhile, the young generation was born in the an open and free society after the Korea had been democratized. So, they accept other people's thoughts easily and are insensitive to the change or reformation. They have more interests in to the music, sports, foreign cultures etc., and express their own personality freely. They vote for the party that have has reformative policies, too.
