North Korean defectors who settle in South Korea find life drastically less satisfying after 10 years, Yonhap reported Thursday.

Citing a Korean Institute of National Unification report, defectors rated life in the South after 10 years 2.73 points out of four. The report surveyed 240 people.

Initially, those who settled into the capitalistic society saw contentment grow to 3.07 points after four to six years from 3.06 in the first three years or less. After seven to nine years in the South, they rated life at 2.99 points.

The report said former North Koreans found adapting to the capitalistic notions of labor, competition, distribution, merit-based society and private property difficult.

There are about 27,500 defectors living in the South.
