This t-shirt contains the global economy, its efficiency, its massive surplus, its hyperconnectedness, and its unsustainability. This t-shirt tells one story of globalization, so let's follow it.

Now, of course, economic interdependence and the accompanying cultural borrowing are nothing new. You'll remember that we found trade documents from the Indus Valley civilization all the way in Mesopotamia.
