2nd week of PR Ethics, Law & Diversity

So I started the textbook Cosmopolitanism and I do believe that Appiah believes in a sense of Communitarianism and that everybody does matter. According to the introduction of Cosmopolitanism there are two factors to the definition of Cosmopolitanism.
First, "we have obligations to others...beyond those to whom we are related to of kith and kind or even formal ties of a shared citizenship."
Second, "we take seriously the value not just of human life but of particular human lives." (Basically the idea that all people are different and we can learn alot from each other.)
As far as the people within corporate America's supply chains, the supply chains consists of groups of people and as I said earlier, everybody matters. In the book, on page 6, Appiah talks about how no "country can produce everything it needs: whatever it has, it is bound to lack something."
Hence, I believe Appiah indirectly is referring to coporate America's supply chains, and we must rely on learning and understanding each other through communication/conversation.
