Many of us say that religion has divided the culture, but our legal system is based on the Greco Roman model, which existed before the Medievals. Following the collapse of Rome, their plan for continuity of government, was to legally-forbid people, to quit their jobs, no matter how bad the working conditions. We are based on the same, failed model, which created the peasant caste.
In case of an emergency, Americans and West Europeans, were said to be traitorous and foolish maroons, if they left the cities. They were supposed to be conscripted into the rebuilding effort -- presumably, against their own, better judgment. The same forced labor, as at the end of Rome, is implied. We assume that it would only last for a matter of weeks, and not for generations, but, when playing politics, one always arrives at logical extremes.
