I work in private industry, and in the private business world it is exactly like an orchestra. You have a boss, and your group is like an orchestra, exactly like Dudamel describes. Companies thrive and the system works. Congress and bureaucracies will never operate as efficiently as private business or an orchestra -- too bad.
"An orchestra is a model for an ideal global society—a symbol," [Gustavo Dudamel] says..."You have to create harmony. Everyone has to listen to each other, this large, complex group of people with different personalities that has to communicate. You have to have discipline. This is where The System works! The point is not to build better musicians. It's to build better citizens, to see children building their lives from music." (from this week's Newsweek).
