My biggest concerns on this article is "He explained that he had a conversation once with Amazon founder and CEO Jeff Bezos about this, and the average time someone stays in job at Seattle is twice as long than it is in Silicon Valley. " Could we say "higher liquidity in labor markets empowers disruptive innovation" or "disruptive innovation needs higher fluid labor markets."? If someone knows the report about this issue, please share with us. Actually, the labor market in Japan is very lower liquidity. The reasons will be that most Japanese prefers stability in their life, and that recruiters in big firms prefer lower number of career changes in a specific period, 5 or 10 years. Concurrently, we have experienced social slumber, so-called "Lost Decade". But, for reference, here is the interesting point about Japan History. When we experience drastic social change, such as The Meiji Restoration and The Defeat in WW2, most Japanese suddenly abandons the preference for stability and drastically drives themselves to creative destruction. Sony and Honda were born right after WW2. 3.11 Tohoku Earthquake might have been a good trigger for drastic social change in Japan.
