25 Korea, Hopeless Country Per capita GDP is less than 100 dollars. The ratio of unemployed people accounts for more than 25% of total labor population. Power generation facilities stand at only one-sixth of those of Mexico. Export is hovering around 2 million dollars, whilst import exceeds 200 million dollars. All these figures indicate that Korea s economic miracle would never happen
