I don't know. It's a good question to ask, especially when looking at, say, the EU with their Schengen Agreement re: free movement of people within and between the signatory nations' territories. If we can move from what we have now to that sort of arrangement among at least the NAFTA partner-nations, that would be an improvement. I can't see it happening with Trump's regime in the States right now, but another administration, one closer in temperament to Obama or Warren or Sanders?
