By that logic, should we not confine the residents of West Virginia to their home state as its coal-based economy collapses? Or should we allow them to move to other parts of the country to seek jobs so that they can lead happier, more productive lives?
Fortunately, for West Virginia, they joined the union and as such we help each other out since they are under federal regulation and are taxed at the federal level.
If we let New Mexico in, why not? Obviously it would require harmonization in many regards, just as we’d require from Canada. Obviously it would have to go through whatever formal process they have in addition to our own process —which typically involves becoming a territory, etc.
I don’t think I’d want to go beyond North America as then it would gather enough momentum to enable a one world government. I don’t think we need that. Nations should be free to follow self determination. A one world gov would not allow that.
Now, Greenland, being a small pop., would be much easier to incorporate into the Union than a Canada or a Mexico.
No, we should try and fix the area and make it better. Throwing your arms up and saying "fuck it, we're leaving" is understandable on an individual level, but on a societal level the effects are devastating.
