What we really need is an EU-style common market for North America. Free trade, free movement of people, single currency, single regulatory environment. Such an entity could compete with any country on earth, from competing for cheap manufacturing wages and costs, (as Mexico is doing quite successfully right now) to competing on quality. English, Spanish, and French are three of the most widely-spoken languages, So most people on earth could find someplace which felt at home for them linguistically, or even if they didn't emigrate here, they would find vendors and customer service people who spoke their language. It would be phenomenally defensible: protected by two oceans and the arctic, it would have no hostile nations on any border, like India, China, Russia, and the EU do. And therefore it would be a region where people feel safe to invest their money. And its currency would be the world's reserve currency. It would have by far the best natural advantages of any economic union in history. If only we could persuade our fellow Americans that Mexicans aren't our enemies, and that we won't all just drop dead if we adopt single-payer health care system.
