The challenge in thinking about this interconnected world is that you have to hold two seemingly contradictory thoughts in your head at the same time. On the one hand, there is something hideous in the idea that so much human suffering could be triggered by the pursuit of something as frivolous as cloves or calico, or that so many manufacturing jobs today could be lost so that our iPhones and 4K TVs could be produced more efficiently in China. But the story also contains a progressive thread woven alongside it, like a double-helix or a braid: that extraordinary capacity that humans have for wonder and delight, for the seeking out of new experiences. That drive — as frivolous as it can sometimes appear — brought us closer to other cultures, and laid the groundwork for new miraculous communities where citizens of every nation of the world live together with a level of peace and prosperity that would have been unimaginable five hundred years ago. Globalism has made it harder for some parts of the US economy to compete, which creates a climate where calls to “Make America Great Again” resonate, just the backlash against the Calico Madams resonated in the early 1700s. And at the same time, globalism has engendered the miracles of our technological revolutions, and the diversity and dynamism of 18th-century London or modern-day New York. Both things are true. Both things have been true for a long time.
