for Economic Co-operation and Development (OECD) average of 4.3%. A strong investment in education, a militant drive to achieve academic success, as well as the passion for scholarly excellence has helped the resource-poor country rapidly grow its economy over the past 60 years from a war-torn wasteland to a prosperous first-world country. International reception regarding the South Korean education system has been divided. It has been praised for various reasons, including its comparatively high test results and its major role in generating South Korea's economic development, creating one of the world's most educated workforces. South Korea's highly enviable academic performance has persuaded British education ministers to actively remodel their own curriculums and exams to try to emulate Korea's militant drive and passion for scholarly excellence and high educational achievement and success. Former U.S. President Barack Obama has also praised the country's rigorous school system, where over 80 percent of South Korean high school graduates go on to university. The nation's high university entrance rate has created a highly skilled workforce, making South Korea among the most highly educated countries in the world with one of the highest percentages of its citizens holding a tertiary education degree. In 2017, the country ranked fifth for the percentage of 25 to 64 year old's that have attained tertiary education with 47.7 percent. In addition, 69.8 percent of South Koreans aged 25–34 have completed some form of tertiary education qualification, and bachelor's degrees are held by 34.2 percent of South Koreans aged 25–64, the most in the OECD. The system's rigid and hierarchical structure has been criticized for stifling creativity and innovation; described as intensely and "brutally" competitive, the system is often blamed for the high suicide rate in the country, particularly the growing rates among those aged 10–19. Various media outlets attribute the country's high suicide rate to the nationwide anxiety around the country's college entrance exams, which determine the trajectory of students' entire lives and careers. Former South Korean hagwon teacher Se-Woong Koo wrote that the South Korean education system amounts to child abuse and that it should be "reformed and restructured without delay". The system has also been criticized for producing an excess supply of university graduates creating an overeducated and underemployed labor force; in the first quarter of 2013 alone, nearly 3.3 million South Korean university graduates were jobless, leaving many graduates overqualified for jobs requiring less education.
