High income earners account for about half of Koreans' overseas spending.
According to a National Assembly Budget Office report, Korea's top 20 percent of income earners accounted for 49-point-six percent of Koreans' total overseas spending in 2016.
The high income group accounts for 38 percent of Korea's total income, and 31 percent of Korea's domestic spending, comparatively less than they spend overseas.
The report recommended Korea boost its domestic tourism and education sectors to help increase the amount spent locally.
