It is one of the most intriguing unknowns that every person who loves their culture wonders about. The indicators it has in the OECD is one of the best, plus its innovation system is the best, even on par with markets like Israel. One aspect that may have helped is the rigid culture and the way they conceptualize life and work. Homosexuality, being a single mother or a divorced woman is frowned upon.
I agree that it is a fast paced society, but as you argue they strongly retain the identity of their culture. It is something that few civilizations possess. Something that has always struck me is that there is civilization within the timeline of the transformation they have undergone. I look forward to reading it. : )
It's always a delight to find someone who shares the same tastes.
