Earthman, come home

About “Earthman, come home”

When the cities left Earth, they moved from a simple environment to one of constant and often extreme change. The universe contained many cultures at different levels of development. The germanium-backed economy and occasional actions by the Earth police kept some order in the spaceways. John Amalfi, who had been mayor of New York for almost five hundred years, never became accustomed to the ongoing crises of life on "Okie" city. This is from a 1955 novel by James Blish.
