"South Korea’s education arms race poses a puzzle. Students spend vast amounts of time and money to move up in the queue for good jobs. But queues are needed only for things that are in short supply. Why should good jobs be rationed? The number of “good” employers should, in principle, expand in line with the scale and skill of the available workforce. So perhaps the preoccupation with educational qualifications reflects problems in the labour market." (Quoted from article)
