Argument: Birthright citizenship outdated; came from period of less migration
Eric Zorn. "Amendment dreamin' and the issue of birthright citizenship." Chicago Tribune. August 12th, 2010: "The guarantee of birthright citizenship (to all but the children of foreign diplomats) in the 14th Amendment came about in an era when our borders were wide open and international travel was considerably more difficult. When a family came here, it was a reasonable assumption that they intended to throw down roots and stay."
