As presented in Global Perspective 15-4, in order to avoid supply chain disruptions, some people suggest that supply chains should be regulated, a bit like public utilities, because countries have become so highly dependent on private-sector production infrastructure. Do you agree with it? Why or why not? Also, it states that there are very legitimate, very good business reasons not necessarily to complete and ship from Asia to avoid supply chain disruptions. Companies may consider other options in other parts of the world even though these may look more expensive. A higher cost structure can make supply chain more robust and reliable. Besides the reason provided there, are there any other possible reasons? What are they? Please discuss and give some examples.
