It may not be replicable: One of the hardest transition that a developing country can make is the transition to middle-class status. Governments have to let go, people start insisting on following their own lights, etc.

Business schools tend to focus on topics that are suitable to blackboards, so they overemphasize organization and finance. Until very recently, they virtually ignored manufacturing.
