Quickly with respect to your question about the race to the bottom and the European model, one thing that's interesting and terrific in some respects about the EU model is that they have managed to avoid the problem of capital flight by gradually developing these sorts of intranational labour rights enforcement mechanisms. This is to say that Europe took as a starting premise that they were not going to create an economic union where certain parts of Europe benefit by cutting labour standards, to the detriment of other parts of Europe. So empirically you don't have capital flight, say, from the wealthier Sweden to Portugal, or even to the former East Bloc countries, which are now part of Europe. Before the East Bloc countries could become part of the EU, they were required to essentially rewrite their labour law and bring all of their standards up to EU standards.
Clearly the distinctions between the Canadian and Central American economies are greater than the distinctions you find in Europe, so it poses an additional challenge. But that's the model you want as your starting premise, so that as you say, we're not going to have a sort of race to the bottom. That's not the basis upon which we're going to engage in international trade.
