I do agree with you that the article has not provided any evidence suggesting the correlation between low birth rate and the expense of education. As an Asian I think the correlation is a little hard to believe for some people but this correlation can be true. The ever-growing economy brings destruction to peaceful Korean society and living expense is going up so much that good salary (and thus having an admirable job) is necessary. If you are not a Samsung engineer you can face social pressure (from your family, your gf/bf family and from your friends) according to the article. This is probably because Koreans are very proud of their technology. As a result from the pressure, I suppose a lot of Korean are avoiding marriage and birth early so they can concentrate on their career growth. These are just my theory and I'd like to see a good research on this.
