One of my great concerns about the pandemic was that it would hinder the global mobility of people and labor, perhaps permanently. Unfortunately, my worst fears are being realized: As Covid mutates, it is affecting not only tourism and business travel but migration more generally.

Consider that after the end of the Vietnam War, the U.S. took in more than 1 million Vietnamese migrants over a 20-year period. After the Soviet Union withdrew its troops in Afghanistan, the U.S. also took in many Afghani refugees, and as with the Vietnamese migrants the results were very positive.
