We live in an interconnected world, dependent on links -- roads, telephones, fiber optic, airlines -- to keep us in touch with the global economy. If one of those links breaks, we are that much less connected to the world, that much further distant from the economy that determines our daily reality.
This is what may happen to 19 small cities in the Midwest, where Delta Airlines says it plans to change or shrink its service or end it altogether. In some of these cities, Delta is the only airline that flies in or out. If it leaves and if no other airline takes it place, these cities will become remote islands in the global sea, as cut off from the mainland as if someone dug up their highways or severed their phone lines.
