I do not disagree with your statements with regards to Korea (they match my relatively untutored understanding), but I would not describe my understanding of Japanese megacorps as untutored, and I find myself in violent disagreement with this line. What's your over/under on what percentage of Toyota Industries' revenue comes from Toyota Motors?
