Truth be told, I'm not quite sure if my position on "open borders" is entirely consistent with the Libertarian Party's position. I would like to see quotaless immigration, but not without specific criteria. Most of all, I want a simultaneous rollback of government welfare so that those who come to America do so with the understanding that they will be responsible for making their own life according to their own effort and abilities.
