text: should the usa, canada, and mexico have a treaty that makes people of all three nations citizens of all three? people could move about in all three nations as they pleased then. sort of like "nafta plus" or closer to eu. i'm not sure about that one. if mexico and/or canada wanted to join the us, then i would be in favor of that perhaps.  i think the us should be open to expanision, but i think it should be others joining our union not an amagamation. mexico's government is deeply flawed. canada's government borders on not being entirely a democracy- their senate is appointed and representation in their lower house is not proportionate to their population.   and opening the south border to mexicans to come and go is such a crazy idea... that it might just work.
