“The reason we are having so many issues in the US,” states ED Hirsch, emeritus professor at the University of Virginia, “is that there isn’t that commonality of culture, and for any human tribe to stick together they need that commonality.”

And in this episode, he explains why that has happened and how we can fix it.
